Time out

I want to take a time out from what is happening here in Israel at the moment and mention a few other personal things.

In yesterday's post I discovered that I had been sent a letter from the Ministry for Social Equity: it contained my 'senior citizen' card, as pictured on the left. This possibly entitles me to a reduction in local authority 'rates' but also allows me to attend lectures and other activities held at a local senior citizens centre.

Although I have reached the nominal pension age, I am not entitled to receive an old age pension yet, because I am still working and my gross salary is above 8,000 NIS. From a financial point of view, it's better to continue working and receive my salary rather than to retire and receive an old age pension along with a monthly payment from my retirement fund. The old age pension is paid regardless of income to all who are 70 years old (and above), so in three years' time, I will be eligible for this. To me, it's slightly amusing and askew, but someone who delays receiving their pension for whatever reason will receive a higher pension than someone who retires at 67 (or 62 if you are a woman). 

The irony of it all is that I don't feel like a senior citizen; I have amended this blog's subtitle to be "I'm not 67 years old, but rather 22 years old with 45 years' experience", which is something that I saw once on a t-shirt. Let's hope that my physical and mental capabilities carry on as they are for many more years.

About two weeks ago, I wrote about completing the "7/4 song", aka "The great escape". The arrangement was somewhat bombastic and featured several innovations (at least, for me), including several tracks for drums, some of which were panned and some not; the snare track had an echo that created an interesting effect. But listening to the song repeatedly (probably hearing it in my head and not so much listening to it) caused me to doubt the suitability of the arrangement; maybe something lighter would be better. So a few days ago I started with a copy of the then final MIDI file, then ripped out several instruments, including the drums and arppegiators, but leaving a few. I then rebuilt the arrangement in a different style, although the solos remain. After having completed this second version (that also went through a few iterations), I am now uncertain as to which version is better; I shall let time decide.

The song can be heard here.

A military funeral

I don't know how many funerals I have attended in my life: at least fifty, probably in excess of one hundred. But I have never attended a funeral like there was today, a military funeral.

Actually, that's not quite true. Sometime in October 1973, I and my group on Kibbutz Bet Ha'emek attended the funeral of a pilot who had been shot down during the war. I remember that I attended the funeral but I don't remember anything else about it.

There were hundreds of people at today's funeral, almost half of whom were in uniform. We heard how Lieutenant Sahar Tal was at home on Saturday morning before he received an urgent phone call to report for duty at Ashkelon immediately. We heard how his father and brother drove him to the meeting point and how he checked later on that they had arrived back home safely. We heard that Sahar was a model officer: shy and humble, but well liked, both by the ranks above him and by those he commanded.

Whilst the army funeral ceremony is somewhat different to the kibbutz version, there are several points of similarity. Even so, I think that we could adopt the final prayer that was sung with great feeling, instead of the same prayer simply read aloud. Then of course there is the three gun salute.

In a terrible sense of irony, an air raid siren (from nearby Bet Shemesh) rang out while we were waiting for the funeral to begin. We were directed to spread out in the cemetery and lie down with our hands over our heads. A moment later there was a loud boom as the rocket landed somewhere close; after a few minutes we were allowed up. A soldier who had laid down near me helped me get up.

Communal grief (2)

Slightly less than a year ago, I wrote about the death of a young kibbutz member; yesterday we were informed that his grandfather, also a kibbutz member, had died. I had worked with the grandfather for several years until his retirement about ten years ago, aged 80. I remember that we held a retirement party for him, in which both people from the kibbutz and work participated. I was asked (in advance) to say a few words; I prepared a speech that was longer than required, as there was so much to say about this person. In the speech (whose text I cannot find), I compared him at one stage to being like a second father: his eldest daughter was born a week before I was, and he would always ask about my studies.

The path that I take in the early morning while walking the dog goes past this member's house. This morning I was thinking about what to write in his memory, and that the kibbutz was fortunate in that none of the outrageous acts of the Hamas terrorists over the past week had affected anyone here. How wrong can one be?

Barely ten minutes ago, a notice was posted on the kibbutz internet site informing us of the death of one of the kibbutz sons, who was serving in the army near Gaza. My wife works with the father of this soldier. I am numb.

The blackest day for 50 years - notes from a peripheral participant

Yesterday (Saturday, 7 Oct 2023), my wife woke me at about 6:30 am - "Wake up, there are booms outside" [booms in this context is the sound and pressure wave of a missile falling to the ground]. We turned on the television and saw the unpleasant and automatic messages from the Home Guard, showing where missiles were falling and where inhabitants had to get to air raid shelters or their internal security room. At first the locations were only settlements near the Gaza border, but slowly more and more targets appeared, further and further away from the border. As our bedroom doubles as the security room, we stayed where we were, but I closed the steel shutters to the window. 

We saw that the locations were getting closer and closer to where we live and eventually the local sirens went off. At the same time, the list of locations included Jerusalem, a location that one would not expect to be targeted (what would happen should a missile fall on East Jerusalem, or worse, on one of the holy sites?). I have no idea of how much damage the 1,500 rockets fired at Israel caused, although I suspect that it was relatively little and that the barrage was more like covering fire.

By this time, the television news company had got its act together and had started broadcasting properly with correspondents situated at various locations. It was then that we heard that the enemy had overrun and occupied at least two kibbutzim near the border. The residents - my spiritual brothers and sisters - were all sitting tight in their security rooms, but this was an event that had not occurred since 1948 when a few kibbutzim were similarly overrun during the war of independence. There were some heartbreaking conversations between the television anchor and frightened kibbutz members hiding in their houses and playing possum. Each kibbutz has a primary reaction force composed of members, and these were trying to engage the enemy, with varying degress of success.

At the same time, filtering in were the first reports about an outdoor festival (what the British would call a rave) that inexplicably had been situated in the same general area. The enemy had arrived at this site and were shooting people; the festival participants had all run away, trying to get away from the enemy and in the hope of finding some shelter. Some survived, some were killed and some were taken prisoner.

Videos (filmed by the enemy) began to be shown of how they managed to breach the border wall, how they were strutting down the streets of Sderot and Ofakim (towns situated about 30 km from the border) and most painful of all, a Palestinian news reporter giving a summary whilst standing in a kibbutz; behind him could be seen enemies looting houses and storage areas, taking anything that came to hand.

All this time, more and more missiles were raining down on the south of Israel. The number of deaths began to rise and rise - 10 dead, 20 dead, 50 dead, 100 dead - along with an even greater number of injured people. One number that was never shown, primarily because of its negative affect on morale but also because it was simply unknown, was the number of prisoners - both soldiers and civilians - taken.

By nightfall, the situation had changed somewhat. There were very few rocket launches after about 4pm, but at 8pm - primary news time - again a huge barrage was fired, causing damage in cities around Tel Aviv. The air force had got its act together and was shooting at enemies trying to return to the Gaza strip along with the more familiar site of tall buildings (that house enemy headquarters) in Gaza being destroyed. Reserves had been called up and deployed at various locations, trying to free hostages and remove enemy forces.

Inevitably comparisons have been made between now and 50 years ago, the Yom Kippur war. Staring us in the face is the complete surprise and lack of intelligence; as the commentators say, this concerted and coordinated attack must have been planned and rehearsed for months, if not years, yet Israel "was caught with her trousers down". On the other hand, there is no comparison at all: then the battlefields were nowhere near civilian locations (especially in the south), and whilst some settlements were threatened on the northern front, the civilian population was never at risk. Yesterday the battlefields were kibbutzim and towns, with rockets raining down on the civilian population.

In the late afternoon, we heard about approaches made by the leaders of the two major opposition parties in the Knesset to join forces with the Likud party and form a time limited emergency government that could make rational and professional decisions about running this war. One leader indicated that the more extreme members of the government would have to leave (mentioning no names but we all know who he was talking about) whereas the other did not mention this. All other legislation would be put aside for the time being. Netanyahu cannot refuse. 

The colossal damage that extremist politicans have caused in the past nine months may have given our enemies the impression that Israel has been torn apart by internal forces and that she is weaker, but in times of war, we are all united. 

It is now 7:52 am on Sunday morning, 8 Oct 2023. I have just received a much-copied WhatsApp message saying that General No'am Tibon [a son of Tzora - NN] aged 62, an anarchist who demonstrates every weekend in Tel Aviv, drove from Tel Aviv in order to rescue his grandchildren who have been hiding without movement for 10 hours in Kibbutz Nahal Oz [a border kibbutz]. On his way, he picked up four soldiers, formed a squad, then staged a battle with five terrorists who were in the home [presumably where his grandchildren were]. He freed the children then drove home. A privileged person. [A fuller and more accurate version of this story, albeit in Hebrew, can be found here.]

This last sentence is extremely sarcastic as one of the epithets hurled at the opponents of the destruction of the judicial system is "Privileged person" - those who had life easy by growing up in a kibbutz and having doors opened for them in later life because they are white and educated... and ignoring the fact that almost all such privileged people served in the army and many reached high ranks. These are the true patriots.

Belated discovery in Delphi: defining indexes on calculated fields

Many years ago, I showed how to define indexes on the calculated fields of a ClientDataSet in Delphi. I haven't had need to look at that code since, as I included the index creation code as a utility procedure in the management program. Today, however, I was working on a different program and wanted to sort the data in a clientdataset in descending order (using AddIndex). When I used the name of an existing field (i.e. one defined in the sql code), AddIndex worked, but when I replaced the name of the field with a calculated field, I repeatedly received an error.

After looking for information on this topic, I finally found the answer: the calculated field has to be defined as an internal calculated field (fkInternalCalc), not as a regular calculated field. Once this has been done, the index can be defined as follows

qSigHarig.Open; qSigHarig.addindex ('idx1', 'thissig', [ixDescending], '', '', 0); qSigHarig.indexname:= 'idx1'; qSigHarig.first;
In fact, it can't be seen from that code that 'thissig' is an internal calculated field, but it is. The documentation is opaque on the difference between these two types of fields and doesn't mention the index problem.

Internally calculated fields, just like calculated fields, are calculated in an OnCalcFields event handler. However, you can optimize your event handler by checking the State property of your client dataset. When State is dsInternalCalc, you must recompute internally calculated fields. When State is dsCalcFields, you need only recompute regular calculated fields.


On a completely different topic, today is the 50th anniversary of the Yom Kippur War (at least, according to the Gregorian calendar). I wrote about this from my very limited point of view ten years ago.

The neuroendocrine system and my blood tests

I've now reached the final section in the first module of my nutrition course: this is concerned with the neuroendocrine system. Some of this material is very important for me, as it mentions the hormones aldosterone and renin that maintain the salt-water balance thus regulating blood pressure. Regular readers will know that I suffer from hyperaldosteronism, which is a difficult word to type and even more difficult to pronounce.

Coincidentally, I have discovered that there are three more sets of results from the blood test that I did a week ago that I hadn't seen previously. The urine test was fine; the hemoglobin A1C % result was 6.0, unchanged from the last time that I had this test done. This is still too high, but if my free glucose level has lowered, then maybe this value too in a few months time will also be lower.

The third set of results were for items that have rarely been tested: Folic acid, Vitamin D, and the thyroid trio of TSH, free T3 and free T4. All are normal except for the free T4 which is too low. What does this mean? Quotes from this site: a low T4 level could mean a diseased thyroid gland or a non-functioning pituitary gland, which is not stimulating the thyroid to produce T4. Since the pituitary gland would normally release TSH if the T4 is low, a high TSH level would confirm that the thyroid gland (not the pituitary gland) is responsible for the hypothyroidism. If the T4 level is low and TSH is not elevated, the pituitary gland is more likely to be the cause for the hypothyroidism. I should say that I don't feel any of the regular effects of hypothyroidism.

I do not want to rush to any conclusions on this topic, so I will not quote the rest of the text. If previously I had wanted to discuss the iron/ferritin results with my doctor, then the TSH/T4 results make this imperative. A fine time to read about the various endocrine glands....

A day spent studying

I took a day off yesterday* in order to continue my nutrition studies. I breezed through the section on the cardiovascular system then followed it by the musceloskeleton system. I tried working on the immune system, which is much more interesting than the musceloskeleton system and also more intimately connected to nutrition (undernutrition interferes with the immune system) but there was simply too much to learn in one go.

Whilst answering the multiple choice questions for these systems, I realised with a very heavy heart that the course requires memorising the material but not necessarily understanding it. The musceloskeleton system material was very much a 'naming of the parts' that makes learning hard but barely contributes to understanding (if not directly hindering).

I noticed a few ambiguities in the texts that were brought to my attention by some of the questions. As I asked, What is the difference between "formation of red blood cells" and "production of red blood cells" (apart from the fact that they have different names)? Formation and production appear to be synonyms.

The final answer that I received was that Haematopoiesis refers to the process through which the body manufactures blood cells. It begins in the embryo and continues for life. This refers to all blood cell types (red, white and platelets). Each of these cells begins with the transformation of hematopoietic stem cells. Erythropoiesis in its simplest definition is the production of red blood cells. It is the process which produces red blood cells (erythrocytes), from erythropoietic stem cell to mature red blood cells. Formation/production/manufacture are all interchangeable. The important factor is the difference between Haematopoiesis and Erythropoiesis. So now you know.

The section on the immune system contained a video delivered by someone whose native language appears to be French. His heavy accent made understanding what he was saying difficult but there were sub-titles that purported to show what he was saying - except that they didn't and contained so many mistakes that I had to give up watching. 'Thymus' (a gland that is part of the immune system) was one time rendered as 'virus' (which really got me head scratching) and another time as 'time is'. There were so many mistakes that I complained on the discussion board for this section; this morning I read that the sub-titles have been corrected and that one can download the slides of the lecture. I think that I'll stick with the slides.

If I'm already talking about the subject of lecturers' accents, then I should recall that in one of the initial lectures about the GI tract, the lecturer (Dutch) kept on calling the second part of the small intestine yeyunum, instead of jejunum. I could understand confusion about pronounciation if it were called the gegunum (is that a hard or soft g?), but the j makes it clear how to pronounce this. So why did the Dutch lecturer 'replace' the j with a y? Unnecessary confusion.

* Although this didn't stop several people from work telephoning me.

A new amplifier for a new guitar

As I have got into the habit of leaving my guitar amplifier in our practice room, I thought that it would be a good idea to buy a small amp so that I can practice at home and also get more acquainted with the various sounds available on the Stagg Tele.

So I looked at various options available from Israeli music stores then I looked at what is available on the Internet. In the end I plumped for the amplifier pictured on the left; deliberately I have given no idea of the scale of this amp, but it occurs to me that the input socket is standard so one can figure out how big the amp is - 12.5 cm high, 12.2 cm wide and 6 cm in depth. In other words, it's miniscule.

The amplifier arrived within 10-11 days of ordering which is very fast. In fact, when I went to pick up the parcel, I had no idea of what I was collecting (because I didn't expect anything yet), although had I been more on the ball, I would have seen that the messages that I had been receiving via Email and SMS originated from the person selling the amp (I almost never look at the name). This cost all of about 85 NIS, plus another 20 NIS for the battery. 

In fact, I was a bit dubious about the battery: the standard 9 volt battery has distinctive connectors whereas the amp had only two small sheets of metal. I put the battery in one way and turned on the amp but no guide light came on. I then turned the battery upside down - this way worked. It seems as if the manufacturer saved a few pennies by not using the regular 9v connectors.

But what does the amp sound like? Very good, in fact. I discovered that the neck pickup on the Stagg that I had previously ignored turned out to sound better than the bridge pickup, at least through this amp. The amp even has an overdrive setting which is basically increasing the gain in the pre-amp stage so that the final sound is distorted. Not bad, but I can't see myself ever using this option. 

Those with a good memory may recall that I wrote several years ago about buying a small practice amp (Aroma AG-03M Rechargable Cube Guitar Amplifier). I looked for this a few weeks ago but couldn't find it which is why I ordered a new amplifier. I wasn't too enamoured of that amplifier because it automatically came up with overdrive and the controls were a bit fiddly. On the other hand, it didn't need a battery.

I am sorely tempted to take this amp with me for the next band practice, saying that I've bought a new amplifier. It's worth it for the joke value.

Incidentally, whilst unpacking the guitar lead that came with the guitar in a plastic bag, I discovered that the guitar did indeed come with two Allen keys, should I need to straighten the neck. I originally wrote that this accessory was missing, or at least was not supplied. Sorry.

Conclusion: a well spent 100 NIS.

The amateur nutrionist

In preparation for yet another appointment with my dietician, I underwent blood tests this morning. I already have most of the results and they make for confused reading. As far as I, the amateur nutrionist, can figure out, there are three major areas being tested, as follows...

Glucose: as far as I am concerned, this is the most important test. I am pleased to see that the glucose in blood level decreased to 'only' 100 mg/dL. This is just below the beginning of the pre-diabetic range (101-120 mg/dL) so this decrease is good. I'm not sure as to what could be the cause of this decrease, but never argue with a good result.

Triglycerides and cholesterol: there is an increase in all of these parameters, which some would say is not good. There are no dangerous levels here, but lower is definitely better; in fact, all of the levels are reasonable, but they have increased, especially the free triglycerides. One of the nutrition books that I read in the earlier part of the summer encouraged the eating of some saturated fat, but I think that I am going to ignore that advice from now on. I think that the increase can be attributed to buying cheese with a higher fat level (15 or 22%), so I'm going back to eating cheese with only 5% fat. 

Iron: this is the most confusing area. On the one hand, the haemoglobin level is 15.6 g/dL, which is a good mid-range level. On the other hand, the ferritin level is very low and the transferrin level is very high. Ferritin is a protein that acts as an iron store, and if it is low, then the body doesn't have many iron reserves - apparently I am suffering from iron deficiency, although not anaemia. The iron level itself is 81 μg/dL, which is at the low end of the scale, but still within the realms of normalcy. Transferrin is another protein that binds iron and transfers it to cells; an over-abundance of transferrin means again that there is an insufficiency of iron. Broccoli is quite a good source of iron, as well as a few other nutrients, but I've been ignoring it lately in favour of cabbage. So it's back to eating broccoli, not that I mind. Recently I've also been eating poached chicken breast that, whilst being a high protein and low fat and sugar food, is also a low iron food, so that will have to stop.

I'll see what the real dietician says when we meet in another week.

"The great escape", aka "The 7/4 song"

On 23 July, I noted the beginnings of a new song, with the imposing 7/4 time signature. Judging by my dated demos, the arrangement came together moderately swiftly, and by 22 Aug, I had what I considered to be the final version of the music.

Words, of course, were a different matter. The primary reason for the lack of words was that I had no ideas about what to write. The secondary reason was that each line in the song has only five syllables, so this became quite an important technical constraint. Eventually one evening I wrote "So the journey starts/To an unknown place/How long will it take?/What will be the pace?", which of course is referring to the process of writing the words - the journey being the process of writing and the unknown place being the destination, the completed lyric. I had no idea how long it would take me to write the words.

Unfortunately, after this belated start, I couldn't progress. I opened a document in which I would occasionally write the odd couplet, but nothing was sticking together, and certainly not for the length of the required lyric. Then another evening had me writing "She knows me so well/Knows the words to say/<missing line>/How to get her way" - this was definitely interesting. This could be about someone who is in a relationship with a woman but is totally under her thumb. There was a third line, but I don't recall now what it was as it was later replaced by something much better.

Walking with the dog on Thursday evening, I found some more suitable lines, and on Friday morning I was finally able to write two verses, each composed of twelve lines each. At this stage, the phrase 'The great escape' popped into my head and I was able to include this: the protagonist is going to make his (or her) escape from the dominant woman. The second verse was more 'physical', describing the escape, with lines like 'chipping at the stone' and 'Shoveling up the dirt'. 

On Saturday morning, I wrote the final verse then started improving the lyrics, by changing words here and there, replacing lines and in one case even changing a rhyming line to a non-rhyming line as I had a better line. There's still one rhyming line that I would like to replace but I haven't found anything suitable yet ('And there are no bends').

When I started singing the words to the melody, I discovered that the tune was pitched too high, from B below middle C upto D, an octave above middle C. Lowering the tune by a tone (now A - C) made it easier to sing. When originally sequencing the song, I had included a middle section; frequently I do this without including a tune, trusting that a contrasting tune will pop up when I write the words. This did not happen this time, so I had to chop out the middle section. Then I discovered that the final bar before the removed section had an Ab chord whereas the next bar (the first bar of the third verse) had a C chord. I had to rework part of the instrumental break between the second and third verses; walking the dog helped me think of a possibility, but in the end it was easier than I thought.

So now I have the music track and I have the words. Despite the odd rhythm of seven beats in a bar, I found the song far from difficult to sing. Now I have to get used to the tune and the words, but that's not too difficult. I imagine that I'll record the first version on Friday, rerecording the vocal until it's good.

Emigration day

On this day, 45 years ago, I emigrated from Britain to Israel. I've already written about the original day (twice, in fact) - see the listings in 'This day in history'. Instead, I want to write about where I was on the 10th anniversary, 1988, as I was doing something quite unusual, at least for me.

I had been called up for reserve military duty in September 1988, presumably a few days after the New Year. To my displeasure, we were to be sent to an area around the Arab city of Nablus, in what some would call the occupied territories and others the West bank. After a few days of revision (mainly target practice), we were divided into groups where each group would help with guarding a Jewish settlement in the area.

My name was not called. At first, I though that I had misheard (i.e. that it had been called and I missed it), but no, I was supernumerary. Could I go home? Of course not. I was told to join the organising staff for the time being, who were quartered in the police headquarters in Nablus. I didn't do anything there, but after the first or second day, I was taken to one of the settlements to guard on a Friday night - this day was my emigration anniversary and I remember talking about it to someone.

Probably I spent Saturday night at this settlement as well, although I don't recall. The next thing that I do remember was going back to Nablus, and as it was now the morning before Yom Kippur, I asked whether I could go home for the fast. I was allowed to do so, and for some reason that I don't remember, I arranged with the person who took me most of the way home that I would meet him again at a certain junction in Jerusalem in two days time. As we would be travelling again, I left my army equipment in his car.

After the fast, I travelled to Jerusalem and waited at the junction where I though that we had agreed to meet. I waited a few hours before I realised that this wasn't the place, so I took a bus to Nablus (there was still such a thing) and reported once again to the police headquarters there, this time without any equipment (although obviously I still had my rifle). I was told to wait and something would be arranged.

The Succot holiday came (as always) about a day after I returned to Nablus, and as no one had told me to do anything yet, I went AWOL and and spent a weekend at home. I returned promptly after the holiday and was about to get an earful from the commander (along the lines of 'you could have gone to one of the settlements and relieve someone else'), when another reservist who also had taken an unauthorised holiday turned up. As he arrived a few hours after me, the commander's wrath was spent on this person and I was ignored.

Eventually I was told that I would be going to a settlement called Tapu'ach (apple), a few kilometers south of Nablus. I was delivered there and started guarding. Several days later my equipment turned up. As there were only three of us assigned to Tapu'ach, we skimped on the hours that we were supposed to guard, allowing one rotating person to be at home. When I returned from my first (and possibly only) official leave, I brought with me a small electric light - this was so that I could read in the evenings in my room (yes, we had individual rooms in an abandoned building). We also had to cook for ourselves.

In this fashion, another ten lazy days passed. Who would have thought 10 years previously that this would be how I spent my time?

Initial sections in the Nutrition course

So far, I've studied the first three sections of the initial module in the Nutrition course, namely

  1. The GI tract and the physiology of nutrient digestion and absorption
  2. Cellular respiration and main metabolic pathways
  3. Fluid and electrolyte balance
At the end of every section, there is a multiple choice questionnaire for self-assessment. I wrote a week ago, "I wonder at what level of detail are the students required to remember", and I've discovered that the answer is "at a very high level". Some of the questions are not strictly multiple choice as they are looking for specific words. As an example of a non-multiple choice question, there is this question from 'cellular respiration': The outer mitochondrial membrane is highly _____ while the inner membrane is _____. My answer was the outer membrane is highly permeable (correct) whereas the inner membrane is semi-permeable (incorrect). The latter answer is impermeable, but there was no way of knowing that this is the answer from the question itself. I suspect that the topic of permeability did not appear in any of the material.

Here's a nasty example of a question from the GI tract section:
Indicate which 3 statements are correct for the gastric phase of digestive regulation by ticking in the box next to it.
  1. The gastric phase describes those stimuli that originate from the stomach.
  2. The gastric phase comprises those stimuli that originate from the head
  3. Gastric phase stimuli include distention of the stomach (which activates stretch receptors)
  4. Neural response: Gastric juice secretion and smooth muscle contraction are promoted.
  5. Gastric secretion and gastric motility are inhibited (enterogastric reflex).
  6. Intestinal secretions, smooth muscle contraction, and bile and pancreatic juice production are promoted.
I chose 1, 4 and 6, whereas the correct answers are 1, 3 and 4. I got two answers correct, but instead of receiving a mark for each correct answer (i.e. 2 marks), I instead received 0. 

My marks were 17/22, 18/22 and 13/13 respectively. I can see the questions and my answers on the website, but I can't figure out how to download them for futher study. I'll have to go over the first section yet again - this is far more complicated than the third.

Trident Studios inconsistency (why was 'Ride a white swan' recorded on 8 track?)

Yesterday I was watching a YouTube video with record producer Tony Visconti diving into the multi-track recordings of two T-Rex songs, "Jeepster" and "Ride a white swan". "Jeepster" was started in Los Angeles and was recorded on 16 track, but Visconti points out that he was used to working with 8 track recorders and so only about 12 tracks were used, leaving 4 empty. "Ride a white swan" was recorded at Trident Studios on 1 July 1970 and was an 8 track recording. Visconti played the various tracks and noted that they initially recorded three tracks of backing vocals that were bounced down to one track, freeing up two tracks.

Wait a minute - Van der Graaf Generator recorded "The least we can do" at the end of December 1969 at Trident studios, at least four months before "Ride a white swan". All of the songs bar one were recorded on 8 tracks, but the final song, "After the flood", was recorded on 16 tracks. There were problems with aligning the 16 track machine which is why recording that song took longer than the others. 

So if Trident had fixed their 16 track machine by the end of December 1969, why was Visconti recording T-Rex on 8 tracks several months later? It's not as if Visconti misremembered, as he played each one of the eight tracks. At this stage in their career, T-Rex was still considered a dippy, trippy act ("Ride a white swan" was their first hit) so Marc Bolan would not have been paying for the recording time. Maybe the record company didn't want to pay the extra cost for using the 16 track machine.

A conundrum to which I will probably never find the answer.

The GI tract and the new guitar

I devoted a few hours yesterday morning to studying the material for my new course, Fundamentals of Human Nutrition and Metabolism. The opening chapter is about the GI tract, that begins with the mouth and ends with the anus. The pre-recorded lectures and accompanying material went into the topic at quite a depth (which enzymes are released at which part of the tract, etc) and I wonder at what level of detail are the students required to remember. There will probably be a multiple choice questionnaire at the end of this section so I'll know soon. After the GI tract, there is material on metabolic pathways (I learnt this material 45 years ago, and since man has existed for several hundred thousand years, I doubt that there will be much new material here) then other systems within the body are discussed. And this is the first unit! I had wanted to continue studying today but that didn't work out. I do intend to spend several hours a day studying during the Succot holiday in another two weeks; also the swimming pool will soon be closed so that gives me a few more hours a week to devote to the studying.

Last night at band rehearsal, I introduced the Stagg guitar. This was my first chance to hear the guitar through an amplifier and so check out the pickups and the various combinations of sounds available. A guitar with two pickups normally has three available combinations, namely neck pickup, neck and bridge, and finally bridge pickup. As the bridge pickup on the Stagg can either be in humbucker mode or single coil mode, there are five possible combinations of pickups. That said, the only good sound comes from the bridge pickup as humbucker; the single coil variant sounds almost the same but less 'full' so there's not much point in using this option. The neck pickup is very muffled and doesn't sound particularly good; it's for when I want to play but not be heard. The tone control goes from a good sound to a very muffled sound, so it looks like I won't be touching the controls very much. Playing the guitar was very easy although at one stage my left hand started hurting; this might be because of the semi-circular neck. I discovered at one stage that the guitar suffers from a mild case of 'neck dive'; having the guitar higher up on my chest should mitigate this. The Stagg weighs 2.7 kg whereas the Washburn is a kilo heavier.

As usual, I had to compete with the wall of sound from the other guitarist, so I couldn't really hear the tonal possibilities of the guitar; was I drowned out simply because of volume or because of the tone? Yesterday morning I had sent to everyone a link to a YouTube video that explains the job of each instrument and how they should play in order to create a good composite sound where everyone leaves room for everyone else. I'm fairly certain that I am the only one who watched this; obviously the others hadn't taken the hint.

It seems almost certain that we won't be playing a show in two weeks' time; this is primarily because the female singer wants to rest her voice (she complained several times during our rehearsals last week) and secondarily because intergrating the keyboard player is going far slower than we had originally reckoned. Had it not been for him, I think we could have already added four new tunes to our original set.

There's another new tune (for us, of course) that we are working on but it's very difficult, being a Greek-influenced tune in 7/8. We spent about half an hour working only on the introduction, so it's far from clear yet whether we will continue with this. Everyone is supposed to listen to it during the coming week so that we will have a better idea of how it is supposed to be.  Maybe our mistake is beginning with drums and not with guitar; the drums are supposed to give the rhythm to everyone else.

Cropping videos

Via Google Photos, I finally managed to download the missing video from last night, 'Autumn Samba'. Having done so, I considered cropping the video, as a large amount of the screen is taken with, on one side the curtain behind us and above our heads, and on the other side the audience. I tried a few online cropping tools; both were very easy, but this one results in a slightly smaller file (although this might be a function of the cropping), but more importantly lacks the watermark of a different site. The file itself is slightly larger than the original, meaning that the phone that made the video compressed the data. The video can now be accessed here.


A few days ago I was watching yet another YouTube video showing how one can improve one's rhythm guitar playing. One of the suggestions was regarding the right hand: keep it moving down and up like a metronome, but hit the strings only when necessary. The samba rhythm is quite complicated, with plenty of off-beats being played; when I look at my right hand in the video, I can see it metronome like, even though I'm not playing all the strokes. In other words, I am playing exactly how the YT video suggests. Like athletes and sportsmen, I can see that I can improve my rhythm work by watching videos of myself playing.

A long, long day

Today started very early as usual with a walk around the kibbutz, giving the dog a chance to do whatever she needs to do. This was followed by a quick breakfast then into the car for a drive to Jerusalem. My wife had to undergo a removal of an internal cyst: not a big problem, but it had to be done under general anaesthetic, meaning that she had to spend the night in hospital for observation. This reminded me of any first day when I used to serve in the army reserves: hurry up and wait. That said, everyone in the hospital was very courteous and helpful, especially the two nurses in the recovery room.

After my wife was released from the recovery room, it was up to the ward: the 'new' wing of the hospital (it's been open for several years) offers single rooms to patients, including en suite bathroom, chairs and even a mattress where an accompanying person can sleep. After she settled in (no food or water, lest she become nauseous or aspirate), I was allowed to leave. I then drove to the music shop in central Jerusalem where I intended to buy the new Stagg guitar. It turns out that the shop is focused on drums and percussion instruments (a drum lesson was underway when I was there), but they also stock some guitars. 

I saw hanging on a wall the same model that I came to buy, but in a natural finish. The salesman said that he found this model at the same time as he found the black one, so he thought he'd bring it out and display it. The black guitar came in a cardboard box, accompanied by a guitar lead but no Allen key (for adjusting the neck) or any other accessories. First I checked the neck to see that it was straight, that the neck was bolted on properly, and that the frets were set correctly and were the right size. The guitar passed the physical tests. The intonation seems ok although there was some buzz when I played the bottom string on its own - I'll rub some graphite into the nut when I change strings, which will probably be soon.

I played the guitar for about half an hour, although only acoustically - there was no nearby amplifier and the salesman didn't provide one. I hope that the electrics are ok. That reminds me: the humbucker bridge pickup has plastic wrap on it that I should remove, although this shouldn't affect the sound.

From Jerusalem I drove home, had something to eat and drink then took the dog for a walk. Then it was down to the dining room air raid shelter for a final rehearsal for the New Year show. Once this was finished, we took the equipment - mainly the drum kit - up to the dining room and set up again. The guitars went through the PA system via DI boxes; the bass guitar was fine but my line didn't work. Eventually the guitar was heard, only for it to disappear then reappear then disappear. When we came to perform, I had to start the first song three times as twice the sound disappeared during the first line.

Again a huge sigh of relief when the show was over. Here's a video of one of the songs; someone was kind enough to film the songs, but for some reason I haven't been able to download the best song on to my computer. Maybe I'll succeed tomorrow.


And most importantly,

GAS

For the last couple of months, I've been suffering from GAS. I don't mean intestinal gas but rather Guitar Acquisition Syndrome. In other words, I've been thinking about buying a new guitar. This is not to say that I want to replace my Washburn semi-acoustic; the opposite is true as I very much like this guitar and the range of tones that I am able to achieve.

Originally the first pains of GAS started whilst looking at the offerings of the store from which I bought my bass guitar. I remembered how easy it was to play a real Telecaster guitar (which I tried when I bought the 12 string) so I thought that I might buy a T-style guitar, for the same reason that I bought the bass. This is how things stood until a few weeks ago.

When I asked my wife what she thought about buying a new guitar, her first reaction was to say that there was no room left in the music room for hanging another guitar on the wall. I then told her that the SG copy has pickup problems and that I won't be using it any more, so that guitar can be stored under our bed and the new guitar hung in its place. Last night I saw a possible extra place on a wall in the music room, so maybe the SG won't get retired after all.

My original thinking was that the new guitar would be little more than an ornament, but in the past few weeks I've been playing guitar more and more often, culminating in the swimming pool performance, with further appearances guaranteed (and I notice that I have hardly played the piano in the past few months, whereas I have been practicing frequently on the guitar). I realised that my semi-acoustic, as good as it is, is somewhat large and heavy. Maybe it would be better to use a T-style guitar when I play standing up. After last night's practice, a smaller guitar would also be better when playing sitting down.

So I looked again at the first store's catalogue and saw that they had a T-style thin-line guitar priced at 1,950 NIS. This is a bit more than I wanted to pay (and the colour is somewhat off-putting) but maybe the advantages that accrue from the thin-line are worth the extra cost, whereas the more standard T-style model costs 1,552 NIS. My 'friend' Shmulik Budagov has comparable models priced at 2,800 NIS (thin-line) and 1,400 NIS (regular) – I wonder why the thin-line model costs exactly twice as much as the regular model.

At this stage, it occurred to me that it would be worthwhile looking for videos on YouTube about these various guitars. The first compared a regular T-style with a thin-line model; the sounds from these guitars were identical. In other words, the difference between the two types would be aesthetic only, and so there seems to be no reason to pay the extra cost.

Then I started looking at regular T-style guitars available in Israel: each shop seems to sell a different brand and at different prices. It was only when I looked closely at the specifications of these guitars did I notice that all feature two single coil pickups. I am not a gear head, but I prefer the warm sound of the humbuckers on the Washburn to the bright and treble sound of single coil pickups. Then I noticed that one guitar, the Stagg SET-PLUS, pictured left, has one single coil pickup and one humbucker, albeit at an additional cost of 110 NIS – a small price to pay for what promises to be an important upgrade (the basic model costs 880 NIS, the PLUS 990 NIS).

I spent some time looking for YouTube videos reviewing this guitar, and all of them say that this guitar is very good value for money; here's one review and here's another, albeit in German. The guitar comes in three finishes: white, black and natural. I was mentally debating between the black and natural finish, so I asked my wife which finish she thought was better from an aesthetic point of view. She also considered the black and natural, plumping eventually for the black. I concurred with her and pointed out that this seems to be the only colour available from the store where I intend to buy this so it's just as well that she chose this colour.

I do not intend to order this guitar via the Internet, as I did with the bass. First I want to play it and see what it feels like before purchasing (one video taught me about something called 'neck dive' that I want to check out). This won't be for another week as the shop from which I intend to buy the guitar is situated in the middle of Jerusalem, and my next trip there will only be in another week's time.
