Guitar thoughts

I have a few mild complaints about my Stagg guitar; I was thinking about them yesterday and may have come across some solutions. First off, the volume of the neck pickup is less than the bridge pickup. Solution: raise the pickup! I hadn't noticed but there are two screws next to the neck pickup, one on each side. These are intended specifically for raising or lowering the pickup. I took a suitable screwdriver and gently turned the screws - the pickup rose (I checked that the pickup does not interfere with the strings, even when played on the highest frets). I will, of course, have to check with an amplifier that this simple procedure has made a positive difference. 

I put a new set of strings on the guitar a few weeks ago; these are "tens" in the professional parlance. I have noticed that these strings are hard on my left hand, leaving deep marks on my finger tips. I think that using a set of "nines" on the Stagg would make the strings more considerate towards my fingers. It's a bit early to be changing the strings again but it's something that I'll bear in mind for next time. Incidentally, the fret buzzing that I noticed after changing the strings has disappeared, presumably because the strings have had a chance to settle down. "Tens" are fine on the Washburn.

It looks like the musical group - I'd like to call it Heptagon - will be playing at the opening night of the Chanuka festival on 7 December. There are some songs that I would prefer to play on the Washburn and some I would prefer to play on the Stagg; I wrote about this here, suggesting that I need a little mixer that would allow me to have both connected at the same time. A short Internet search found what I was looking for; after I ordered it, I realised that it's basically the same as the headphone amplifier that I wrote about several years ago, except that the headphones mixer is stereo and I want a mono mixer. But I probably could use this mixer for the guitars if I decide to take both (this may seem like overkill). Something else to check.

As it happens, I ordered a few extra guitar leads including one short 0.5 metre lead a few weeks ago; even though this was from an Israeli shop, they still have yet to arrive ("there's a shortage of drivers", I was told when I phoned last week to check), although they are supposed to come in a few days' time. Just as well, as the extra leads will help me check how the mixer works, and also because last night I was having trouble with my usual guitar lead. I swapped this with another lead that I have in my guitar bag and the problems went away.

An obscure seventh chord in the wild

A month ago, I wrote a blog showing various seventh chords, including a few that are more notional than useful. As it happens, the musical group is working on a song (by my fave Yoni Rechter) than includes one of the rarer seventh chords - C7b5. This chords appears at the end of a line and is then followed by a row of chords descending by a semitone. At first I thought that this was a misprint in the chord chart to be found on a public site (i.e. not that of Rechter) as other songs on this site often have errors in the chords posted, but after thinking it through a great deal, I realised that this indeed is the chord. The melody note played over this chord is F#, and indeed this chord contains an F# (or more accurately, Gb, as it's the G that is being flattened). I tried a few other chords that contain F# but none of them sounded correct.

I saw an interesting YouTube video about a week ago that states as the basis of a school of harmonic thought that all music is based on tritones. For example, the perfect cadence (e.g. G7 -> C) has a tritone in the G7 (B, F) resolving in the C (C, E): that's what makes it sound so perfect. As I tend not to have perfect cadences in my songs, I noted the idea about tritones but didn't think about it very much.

C7b5 is a great example of a double tritone chord: any dominant seventh chord (e.g. C7) is going to contain one tritone (in this case, E, Bb), but this chord has a second tritone (C, Gb). That second tritone would not resolve normally by a semitone if followed by an F chord. The double tritone also makes it difficult to figure out a chord shape for the guitar - one doesn't want the E and the Gb on adjacent strings, and similarly not the Bb and C. In the chord diagram at the top, the shape on the right is probably the one that I will use as I can lower it by semitones as required by the song. The notes, from bottom to top, are C Gb Bb E - this has all four notes, and no two notes are separated by a tone.

After trying out the various shapes, the chord on the left seems the most appropriate. The notes are C, Gb, Bb, E. I actually developed this shape myself before noticing that it was one of the shapes in the picture.

Network upgrades and printer problems

Over the past few months, the kibbutz has been updating the internal network wriring: instead of utilising the old copper cables that were laid down for telephones, the "optic fibre to the house" project has been upgrading everyone's connection so that they will have an optic fibre cable from the main network server to the house. This should improve connection speeds by a factor of 10. Due to the war, there were a few weeks in which nothing happened, but in the past two weeks, four houses a day (which means 16 households in most cases) have been updated. My turn came at the beginning of last week.

One day a team installed the physical cable that comes out of the wall one metre from where I am sitting. A few days later, another team turned up with a new optical router that takes as input the optic fibre and provides four ethernet ports as well as wireless access. Two computers are connected to the router by network cable, so they didn't notice the change. I ran wireless network detection on my mobile phone to find the new network name ("noam_wireless_5GHZ") and connected the phone without problem. One computer that connects by wireless also found this network and connected. But on another computer, the only network detected still went by the name "noam_wireless", even though the previous wireless router had been disconnected both from the network and from the electricity. After rebooting the computer, I tried connecting to this old/new network; the connection was successful, and I noticed that transferring a large file via AnyDesk worked much faster, so obviously the computer is connected to the new network.

But my printer had disappeared (not physically, of course). I couldn't figure out how to reconnect to the printer, or more accurately, get the printer to connect to the new network. My original blog on the topic was not useful: "I failed to connect the printer to my wifi: I gave it the network name and password but no connection was made. When I installed the printer driver on the computer, it gave the option of accessing the printer via its own wifi.And lo and behold: I can now print from my mobile to the printer via the magic of wifi!".

The printer is connected via USB cable to one of the computers that connects to the network via cable, so I thought that I should be able to use this connection in order to change settings on the printer. I don't remember exactly now, but I think that I was unsuccessful in this. On the other hand, I was able to access the printer via its own wireless network; I connected my main (wireless) computer to this network then pointed a browser window at the printer's address. I couldn't log on as administrator at first, so I had to reset the password on the printer itself (this is explained in the printer's manual). Once I had opened the browser window as administrator, I redefined the local network, but still couldn't get the printer to connect to this network. I did discover, however, that a file that I had sent to the printer got printed when my computer was connected to the printer's network. 

At the same time, I noticed that the toner capacity was at 0%, so of course I had to change the toner cartridge. I wrote in that blog from 18 months ago that I ordered a replacement cartridge from Amazon; when I opened up the box, I discovered that the cartridge was model PA-211. Despite being touted as suitable for my printer, I received an error message after I installed the cartridge. So I was forced to order a new cartridge from an Israeli supplier, this time insisting on model PA-210, which is the number of the original cartridge that I extracted from the printer.

This arrived the other day (i.e. within a few days of ordering), and today I had the time to install it; the printer accepted the new cartridge gracefully. Then came the time to try and reconnect my computer to the printer: I opened up the control panel on my computer and went to the 'devices and printers' section, choosing 'Add a new printer'. Three printer types appeared (presumably this means that their drivers had been installed previously); I chose the Pantum printer, waited a few minutes ... then saw that I (or more accurately, the computer) had a connection to the printer. I sent a test page and saw it print. This presumably is what I meant when I wrote last year "it gave the option of accessing the printer via its own wifi", although now I didn't see such an option. Maybe the printer driver was still defined as accessing the printer via its own wifi, so the driver looked for the printer's network signature, found it and connected my computer. In other words, this seems to have absolutely nothing to do with changing to an optical router. I should point out that I connected the printer to the optical router with an ethernet cable, although I have no idea whether this made any difference.

Hopefully now the only maintenance that I need perform on the printer is changing its cartridge once a year.

The musical group reconvenes

Due to the Jewish holidays, the musical group took a break from 17 September onwards, intending to recommence rehearsals at the beginning of October. Of course, the events of 7 October were such that no one felt in the slightest bit interested in playing rock music; nothing was said but there were no rehearsals. 

About ten days ago, the bassist sent a message to our WhatsApp group, suggesting that we start working on new material, possibly for a performance during the kibbutz's 75th birthday, possibly for Chanuka and possibly for a performance intended to raise public moral. I posted back saying that I had had similar thoughts, but that we should ignore our previous repertoire and work on a more 'unplugged' set of songs that would bring a message of hope and peace. We then entered a phase of suggesting more and more songs; last week we worked on three songs quite deeply, and one we barely touched. Presumably tonight we will work on that one song that we agreed upon as well as two others.

As these songs are quieter, or rather less "rocky", I decided to fingerpick most of them. I admit to finding it difficult to fingerpick well on the Stagg; the fingerboard is narrower than what I am used to and the strings seem to be at a higher tension. This morning I tried out the three songs from last week and found it much easier to play them well on the Washburn. So I'll take this guitar tonight.

This makes me wonder whether I'll end up taking two guitars to any public performance - in which case I need a way of switching between them quietly. I bought a small mixer several years ago but I was very disappointed in it as it seemed to suck all the tones out of the sound. Maybe I can find another one that will be more suitable, although of course there's no real way of knowing in advance how it will affect the sound.

Counting beats with Van der Graaf Generator (4) - Whatever would Robert have said?

This song starts in classic early VdGG style - ethereal organ, breathy saxophone, acoustic guitar accents. There's only one other song that starts like this - "Boat of millions of years" - that was relegated to the b-side of the single "Refugees". Both of these songs were on the "1968-1972" sampler that I had and played to death during 1973.

Most of this song is clearly in 4/4 time; in fact, the pentatonic scales played by the electric guitar make it the closest to a normal rock song, especially in the period 4:00 - 5:00. But this section is followed by a short organ break whose time signature I have never managed to figure out. This section appears at the end of every verse, but is so fast and over so quickly, making it hard to analyse.

The YouTuber played this song on his channel and table-drummed the rhythm. I fell off my chair laughing as it seemed to be the 'America' rhythm - a bar of 6/8 alternating with a bar of 3/4. Why not? After all, in a few years time, the group Yes would set the opening of one of their more famous tunes ('Yours is no disgrace') to the rhythm of 'Bonanza'!

I thought that I would check this against listening to the song a few times; I was disappointed to discover that whilst there is an influence of 'America', that's not what's being played. As far as I can determine, it's one bar of 6/4 (?) with the first half being played fast and the second half slow.

Whilst there are sites that give (more or less) chord charts for several VdGG songs, none of them give the rhythms, so I can't check what I feel.

For those who don't know, the eponymous Robert is Robert J. Van der Graaff, who gave the band its name (along with a misspelling).

Wartime radio

When the country is facing difficult times, the radio stations play sad or thoughtful songs, ignoring all the raucous material that they might normally play. As a result, there have been several songs played that are also in my personal playlists, something that normally occurs extremely rarely.

About once a month, the 'Unhalfbricking' version of 'Who knows where the time goes?' gets played, but recently I heard what must be the original version from 'Sandy and the Strawbs' as it was only Sandy playing acoustic guitar and singing the original arrangement. I wonder how on earth the station managed to lay their hands on this version - it didn't come from me!

Nick Drake also gets played about once a month; normally this is 'Northern Sky', but over the past few weeks I've heard 'Day is done', 'Way to blue', 'Riverman' and 'Saturday sun' from his first album; 'At the chime of the city clock' from his second album was played last night, and 'Pink moon' from his eponymous third album has also been played.

Maintaining the Joe Boyd/Witchseason connection, I also heard a John Martyn song one evening. I didn't recognise the song (I wasn't listening closely) but it sounded like the style of 'Bless the weather'.

Yesterday I heard 'Colours of the sun' by Jackson Browne; I don't think that I've ever heard him on the radio here. We do occasionally hear Joni Mitchell - apart from the favourites 'Big yellow taxi' and 'Both sides, now', I heard 'California' recently.

Randy Newman also gets played occasionally. Twice I've heard 'In Germany before the war', that presumably was chosen because of its melancholy violins and clarinets. It certainly wasn't chosen because of its lyrical content, and I imagine that the song would be dropped should someone listen to the words and understand them - they're about a child killer.

Yesterday was played The Beatles' 'The sun king' followed by Fleetwood Mac's 'Albatross'. I couldn't hear if the presenter (if there was one) talked about the connection between the songs, but it would be better if 'Albatross' were played first followed by 'Sun king' as the latter was influenced by the former.

I did hear one Saturday morning a somewhat upbeat tune: at first this seemed to be a typical 'soul' number alternating between the I and IV chords, but suddenly the song took an extreme left turn into the sort of chord progressions that I write. I had enough presence of mind to whip out my phone and record part of the song for later identification (I don't have Shazam on my phone). When I listened to the recording, I guessed that I was listening to a song titled something like 'something to talk about' and indeed this was the title of a song by Bonnie Raitt (not someone who I have ever consciously listened to). What are the chords: A D A D (this is the straight part) F#m G F#m G C F C E. In Roman numeral form, this is I IV I IV vi bVII vi bVII bIII bIV bIII V. The second half of this verse is straight out of my songbook.

I want to finish this blog entry by quoting the words to a song that was played a few weeks ago; it's a song whose opening verses I have often sung to myself this year.

Many's the time I've been mistaken
And many times confused
Yes, and I've often felt forsaken
And certainly misused
And I don't know a soul who's not been battered
I don't have a friend who feels at ease
I don't know a dream that's not been shattered
Or driven to its knees

But it's alright, it's alright
For we lived so well so long
Still, when I think of the road we're traveling on
I wonder what's gone wrong
I can't help it, I wonder what has gone wrong
("American tune" by Paul Simon)

Fortunately this war seems to have consigned the 'judicial reform' to the dustbin where it belongs. Nothing so unites a fractured society than a war ... although in America of the 60s, a war caused the society to fracture.

YouTuber's first listens to Van der Graaf Generator

There are several people who make YouTube videos of their reactions to listening to a piece of music for the first time. I have to admit that I don't find most of these videos very interesting or valuable, but there is one YouTuber who has started listening to Van der Graaf Generator, and intends to listen to all of their music (I think that he is referring to the 1970s incarnation of the band and not the 21st century reformations). I have just found out that these videos are three years old ... but then the music is +/-50 years old!

Today I was listening to his take on Man-Erg, which is definitely the most accessible track from the masterpiece Pawn Hearts album. I admit that I don't find the commentaries very illuminating, but this time the commentary was very much on the ball. Leaving aside the superlatives, he said "I've kind of said this before, but out of all the progressive bands that I've listened to, here on the channel, and of course on my own, I do feel that Van der Graaf Generator is the most cerebral. They're the most mental - and I don't mean 'mental' in a crazy or insane way - I mean 'mental' and 'cerebral' in that their music, Peter Hammill's lyrics, cut down to the very core of what makes a human tick. What goes on, psychologically, inside of the mind. Because his lyrics just literally cut deep right into that. I think that's one of the things that separates their music from other progressive bands. Yes, the music itself is definitely different. I love the spacey vibe that they have in their music; they have this interesting way of building atmosphere in their music that I want to explore deeper .... It's that cerebral kind of creativity that they have that I think is hard sometimes to get on a first listen ... some songs are going to take longer to connect with you, some songs take longer to understand .... They may be one of those difficult bands to get into right away, but I also feel that once they click for you, they're also going to be the most rewarding" (13:12-14:42).

I couldn't put it better myself. In fact, I've never really been able to articulate my feelings about these songs. I used to say to myself that "Pawn Hearts" contains "the complete human condition", but that's a bit glib. Listening to this video pulled me back to when I was 15 and listening to this record constantly for a few months. There was so much wonder at the world that the words and music conjured up. 

Unfortunately, a bit later on, I started listening to the music in a more analytical way, figuring out the chords and the rhythms, and along the way losing the holistic view.

I have always held VdGG to be in a different dimension - none of the two guitars, bass and drums 4/4 rock. The music is impressionistic; it's still music, of course, and can be analysed, but it has the same relationship to 'regular' music that the impressionists' paintings have to general art. I like the impressionists, both in art (e.g. Monet and Cézanne) and in music (Debussy and Satie), more than their more traditional colleagues.

Restringing the Stagg guitar

The day that I bought the guitar, I wrote 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. Restringing day has come and I thought that I would write about it, as it has some differences from restringing the Washburn or any other guitar that I own.

The first difference is that the strings are "through body": this means that instead of having the strings anchored behind the bridge, as shown in the accompanying picture, they are fed through the body of the guitar from the other side. To quote a random person from the internet, I do think that the string through design puts more of the string into contact with the surface of the bridge saddle, and that probably helps keep the string from sliding around. 

This meant, of course, that I had to extract the strings via the holes pictured on the back of the guitar. Five strings came out easily but one got stuck and it took no small amount of fiddling before I could pull this string out. 

The other problem is also another 'Fender feature': the Washburn et al. have a tilted headstock with three strings of each side that helps maintain tension on the strings. But Fender, in their wisdom, have six strings in a line without a tilted headstock so they make use of a string tree. As the Stagg copies the Telecaster design, it too has a straight headstock albeit with two string trees.

I thought that I would have to remove the string trees in order to remove the strings, but it turns out that once the tension is reduced on the string, it can be pulled out from under the tree. I'll remember that for next time.

Normally I would clean the fretboard after removing old strings and before adding the new strings, but as this is a new guitar, there was no need for this. I did discover, however, that there was plastic film covering the neck pickup, as there was for the bridge pickup. I removed this film before continuing.

When all the strings were off, I rubbed a pencil on the nut: this is supposed to increase friction and prevent buzzing. Then I put the new strings on, starting from the lowest and up to the highest. For a change I had bough "Fender" strings; normally each string in a set comes in its own envelope, but here there were three sets of two strings round together. One differentiates between the strings by the different coloured ball at the end of the string (this holds the string in place at the back of the guitar).

Here I could have done with three hands: one hand to hold the guitar, one hand to thread the string through the body and out through the saddle on the other side, and one hand to pull the string. I managed to thread the strings through the body, over the nut, under the tree strings and into the machine heads without too much trouble. After leaving the guitar for a few minutes to settle, I then approximately tuned the guitar, although I know that I will have to do this again tomorrow.

There is a nasty rattle coming from the bridge when I play any of the strings. I think that this is because the strings aren't sitting properly in the saddle - this is much more obvious on a 'normal' bridge. I pushed each string down just in front of each saddle in the hope of reducing this horrible sound (that probably won't be amplified). I'll see how it sounds tomorrow.

So I've now learnt how to restring the Stagg. For those who care about these things, I'm using a 10 - 46 set.
