A young persons guide to the guitar

Filed under: Guitar, Listening — Sean @ 4:18 pm

I’ve been pondering a little on musical influences. In the UK we have (had? Not sure if its still running since I rarely subject myself to pumped media these days), a long running radio programme called ‘Desert island disks’, where they invite guests to burble on about themselves and introduce a selection of their favourite tunes, the premise being if they were marooned on an island, what music would they want to have with them. In this day and age of iPods and the like of course, we have become accustomed to carrying around with us a vast library of music, so the concept might seem a bit odd to younger readers; but there was a time when music, at least in my life, was hard to come by.

I still recall saving my pocket money for months to afford my first album: “Dark side of the Moon” by Pink Floyd. It would have been early ‘74, and I would have been 12 years old. And then when “Wish you were here” came out, I had to negotiate an extended repayment system with my mother in order to get it. When everyone was out I would listen to that album in the dark at immense volume, with just the little red light on the amp to focus on. Complete zen immersion. I had no inkling that mortals could make music like this. I can still vividly remember the day I visited our neighbours across the road, he was a Brummie and was playing an album by a little known band from his home town, “Black Sabbath”. Well when I heard that, my life changed forever.

By the time I was 15 I maybe had 10 albums of my own. My brothers probably had a similar number, and our tastes dovetailed quite well so there were maybe on the order of 25 albums in the house I could listen to – My stepfathers collection of Sinatra and related crooners being of little interest to me; and of course a handful of tapes made from albums borrowed from friends. There was precious little on the radio that interested me except for fuzzy reception of radio Caroline late at night and in later years sometimes I could get to listen to Nicky Horne’s “Mother wouldn’t like it” on Capital radio, which would play an eclectic mix of rock music.

Now I know I’m severely at risk of sounding like the old farts in the classic Python sketch here, “had to walk 7 miles in the snow to school even in Summer, uphill both ways and lived in a cardboard box in’t middle of road”. As my kids like to point out at every opportunity, but the fact remains that music, and in fact information of all sorts, was pretty scarce in those days – at least to me in the cultural wasteland of a suburb town where I grew up. What would I have given for Wikipedia when I was a kid.

So, since I’m never likely to be invited on to Desert Island Disks, here is an annotated list of my top ten tracks I’d like to send to that 12 year old boy (unless of course I can just send him my Zune), I know he would have appreciated them, you might like to try this exercise yourself.
So in classic “Top of the pop’s” reverse order:

At number 10: “I’m Going Home” by Ten Years After. Probably the definitive recording of this is the one form from Woodstock, which blew my mind when I first saw it (on film – I’m not quite that old!); but the recording I’ve grown rather fond of over the years is from the Live at Filmore East album. They say the blues is supposed to be a melancholy form of music, but not the way Alvin Lee plays it, which is more like a cheerleader on speed.

At 9: “1952 Vincent Black Lightning” by Richard Thompson. Now young Sean might not have appreciated finger style acoustic guitar quite as much has his later self does, but this is a masterpiece of the singer-songwriter’s art and I’m sure he would have quickly come to love it. My favourite version of this was recorded from an Andy Kershaw session for the BBC back in the mid 90’s, which i don’t think has been commercially released, however the recording on the album “Rumor and Sigh” is pretty fab too.

At 8: “Eruption” by Van Halen on the eponymous debut album. Now this is a bit of an oddity in this list, because this was one of the albums I actually had when it came out (still have in fact), however the point of including it here is that although today it’s a bit of a cliché, and you can hear 12 year old kids playing it in guitar shops now; when I first heard this at the age of 15/16 it was like the Martians had landed. I mean I had NO IDEA how a slab of wood with wires attached to it could make noises like this. The cheapo Kay acoustic I was struggling with certainly didn’t. I’d like to send this to myself at the age of 12 with a half decent electric guitar and explanations of what hammer ons, pull offs, right hand tapping, whammy bars, string bends and monster amplification actually do. Genius. Unfortunately as far as I’m concerned the VH band never really lived up to the promise of this debut album, spiralling off into the excesses of 80’s pomp rock, but at the time this was a watershed recording.

At 7: “Shin Kicker” by Rory Gallagher from the live album Stage Struck. Now that’s how to open a set. Strangely Rory was someone I heard a lot about as a kid, but never actually heard play. I wish I had, I might have gotten to see him play before his untimely death.

At 6: “If I could Holler” on the album of the same name by Catfish Keith. This is someone who deserves to be better known; an absolute master at putting a fresh spin on old school blues and spiritual music. I could put probably any of his recordings in this list, and struggled trying to pick one. This however is just achingly beautiful; put it on your bucket list to see him play live.

At 5: “Supernaut” by Black Sabbath from the album Vol 4. Again an album I did in fact own as a teenager, but I wanted to include Sabbath here because they were so influential on me, and of course so many others. I picked this particular track out, although the same point is true of a lot of the Ozzy era Sabbath, because I find it interesting that although Sabbath had a reputation of being uncompromisingly heavy, to me their music was never sad or doom laden. I wish the thrash metal brigade would stop thundering out a single idea as fast as they can and that people would start making stuff like this again, speed and volume are no substitute for talent. Iommi puts more ideas in this one track than some bands put in a whole album, but it’s not tricked out Phrygian mode widdlings in 25/32 tempo either. His playing is open, lyrical, even paced and amazingly delicate for the so called progenitors of Heavy Doom laden metal; the musical equivalent of Shaker furniture, to my ears at least.

So now we move into the super league. These next four tracks are my all-time top favourites; to me they represent the absolute pinnacle of what playing the guitar is all about.

At 4: “Driving South”, the Jimi Hendrix Experience from the BBC sessions recording (disc 1). This is one track where the louder you play it the better it gets (legend has it when they recorded it they received complaints that it was too loud from people working 3 floors below). Jimi of course would be in pretty much anyone’s top 10 guitar list. I think it’s impossible now to appreciate quite how big a deal Jimi’s playing was at the time, and just about anything he recorded is magical, but this track to me epitomises his (and the band’s) playing, it still sounds fresh as a daisy today; it goes like a train, and is just unbelievably good.

At 3: “Little Wing” by Stevie Ray Vaughan on the greatest hits album. (Kind of unfair that Jimi gets in twice but then he is that good). Stevie of course would again get in on merit in any guitarist top 10, but this track stands out to me because he is playing Jimi’s music. The love and respect that Stevie had for Jimi just shines through in every note here. A thing of beauty.

At 2: “Pantomima” by Carlos Paredes. You might struggle to find this one, it’s on an album called “Guitarra Portugesa” from 1990 put out by EMI but not on all versions. Not well known outside his native Portugal, Carlos’s playing here is simply breath-taking. He is not playing a six string guitar, but the Portugese guitar, a very interesting sounding instrument. This particular track is unaccompanied, and has a roll in it about half way through which still gives me goosepimples whenever I hear it. Wonderful stuff. I wish I could have packed young Sean off to Portugal to study with Carlos.

At 1: “Ship Ahoy” by Frank Zappa on the “Shut up n play yer guitar” double album. What can I say about this? When I got this album I must have played this track back to back in the headphones for about 2 hours. I think this is the most astonishing musical statement ever made, I never tire of it. Even now 20 odd years on it still blows me away. If they don’t play this in heaven, I don’t wanna go.

There you go Sean, a little gift from me to me, hope you enjoy them

Sunday Assessment for 3rd Jan

Filed under: Guitar, playing — Sean @ 6:01 pm

Today I started thinking about playing and a new approach to my practice. It is my goal to assign Sundays for continuous assessment and goal setting. Since I didn’t set any goals last Sunday, it being the festive season and all that; this first assessment will concentrate on explaining the routine and how I intend to apply it. Then I’ll lay out my actual practice schedule, should any of you want to follow along.
I’m going to be following my own practice routine, one hour per day after breakfast; but it’s going to be based around a bunch of books, and the excellent free tutorial site provided by Justin Sandercoe.

The books I’ll be using are: Chord Tone Soloing and Guitar Fretboard Workbook by Barrett Tagliarino (CTS & GFW ), Creative Guitar 2 by Guthrie Govan (CG2), and Guitar Secrets by Joe Satriani (GS). If you are intending to follow along, you might want to get a copy of these (I got a couple of them for my Birthday, thank you Alice – oh the power of Amazon Wishlists!). If you decide to get your own copies (which will be essential to follow along, as I’m not about breach copyright by posting them wholesale here), you should order them through the Amazon links on Justin’s website so that he’ll get a small kickback which will enable him to keep on posting.

Note that although as I stated in a previous post, I’m by no means a competent guitarist, I have got quite a bit of stuff under my belt already and although my skills are what you might call patchy, I’m not starting at ground zero here. If you want to follow along and you don’t know what an A chord or a major scale is, you’d probably be advised to work through Justin’s beginner’s course first. I won’t be covering basic chords and stuff, although I may well be incorporating some bits from that series too as revision for myself.

Each week I’ll be recording myself playing the exercises that I set on the previous Sunday and maybe even posting them here, those that don’t pass muster to my own ears will get carried over into the next weeks regime; those that I deem acceptable, or I’m just plain sick of, will be replaced by newer exercises (or old exercises for revision). The amount of success each week will determine the size of donation I will be providing to Justin! (your own conscience will dictate the size of any donation you’d like to make).

So the main feature of this regime, as recommended by both Barrett and Justin, is small bite size but intense sessions of 5 minutes each focussing on specific activities, interspersed by two minute rests over the course of about an hour. Barrett is quite insistent on this in fact, recommending using an egg timer to ensure you don’t run over; he gives a lot of justification in the intro to the chord tone book on why this discipline will keep you motivated, which I won’t repeat here but you can check it out for yourselves when you get the books. I think it sounds like excellent advice, and I have already co-opted our kitchen timer to try it out. The other essential piece of kit is a metronome. I have one built into my Korg Pandora unit but I may get a simple battery powered one as well, as some of the exercises involve working to a flashing light rather than a click track.
So, here is the first week’s study sheet.
Warmup
Finger Gym 2 mins
Spider 2 mins
A minor pentatonic Scale (60bpm) – CTS p9, 2 mins
Harmonized C Major Scale – GS p7, 2mins
break – hand stretch 2 mins
Left Hand
5 root shapes exercise in G GFW – p8 5 mins
5 root shapes exercise in A 5 mins
break – breathing 2 mins
Right hand
Alternate picking 1; 40 bpm CG2 example 1.2 5 mins
Alternate picking 2; 40 bpm CG2 example 1.3 5 mins
Alternate picking 1; 80 bpm 5 mins
Alternate picking 2; 80 bpm 5 mins
break – shoulder stretch 2 mins
Listening
Solo notes over A and D CTS p7 ex1 5 mins
Lead in’s to roots CTS p7 ex2 5 mins
break – breathing 2 mins
Repertoire
needle and the damage done 5 mins

So that’s the plan, see you next week for the first assessment.
As a postscript, I haven’t done any more work on the Ghettocaster after my resounding success with the chisel yesterday; but I did spend half an hour designing a headstock logo. Not sure if I’ll actually use it, but I thought you might like to see it anyway.

Gotta pick a pocket or two boys…

Filed under: Guitar, building, ghettocaster — Sean @ 6:41 pm

Today we were supposed to be going down to visit the in-laws for lunch, but a generous sprinkling of the white stuff in the night meant that the hill up the lane was too slippy to drive up.

Lane covered with snow

So we got stuck halfway up, and I had a fairly hairy experience backing down the hill again, trying to avoid sliding off the side into the field 50 feet below. So, after strong a cup of tea to recover, I suddenly found myself with a free afternoon. And what’s this, a chisel in my hand, hmm….

OK, I’ve measured the distances about 50 times, and I’ve convinced myself where the additional pocket needs to be to accommodate my chosen pickup position as discussed yesterday. You can see in the picture that it will not quite double the width.

pocket marked and showing neck position

Well that was the before, and about 40 minutes later, this is how it looked.

wider neck pocket

and heres the pile of chippings extracted

pile of chippings

OK, so not quite as neat as before, but I’m quite pleased with it actually, given that I probably haven’t whacked a chisel in anger since wood-work classes at school umptedum years ago, and once I install the copper sheilding and the pickguard no ones going to see it. Inspires a bit more confidence that I’ll be able to make a socket for the bridge pickup without screwing it up. So I think that’s that decision made. I haven’t been able to find the pickups I took out of beastie when she got a bit of an upgrade a few years back, although I’m sure they are in the loft somewhere, but actually since they are the original super 70’s, I probably would keep them in case I ever decide to return beastie to stock. And besides, Tele bridge pickups actually hang off the bottom of the bridge metalwork so they would be a bit wrong anyway; so it looks like shopping time again, these barenuckle pickups have had good reviews, so they are front runners unless an eBay bargain presents itself.

Here is a shot with the neck pickup held in place with a bit of blu-tac.

So first blood is drawn (well not literally you understand, although I did manage to whack the side of my thumb quite nicely with the hammer), onwards and upwards…

Pickup Lines

Filed under: Guitar, building, ghettocaster — Sean @ 3:53 pm

Today is the first day of the new year, and I have been musing more on the Ghettocaster. In the previous article I described the overall design aesthetic I’m looking for. But if the thing is going to function as a proper musical instrument it also has to follow the design rules of a stringed instrument. The primary function of an electric guitar is to convert the vibration of a metal string into an electrical signal. Thus I need to understand a little bit about how a string behaves and how a pickup works. A couple of good reference articles I found which explain this in a lot of gory detail here and here. A general basic introduction is here.

I can’t pretend I followed everything in the Tillman articles, but the basic upshot it seems to be that a string vibration consists of a number of different segments which generate the fundamental tone, and a series of harmonics above it, and the type of pickup used, and more importantly its position with respect to those segments (as well as the mix between multiple pickups if present), is the main determiner of the sound of the guitar.

But whereas most guitarists are looking for a complex mix of higher harmonics, mixing bridge and neck, and sometimes middle signals; with single pole and humbucking arrangements to try and reproduce signature tones of classic electric guitar tracks, the Ghettocaster’s main role in life will be as a control device going into the computer. Thus I want to have a fairly strong and pure fundamental tone so that it works well with my Sonuus MIDI converter, and for actual guitar tones, I’ll be using my little Korg box, or Guitar Rig – which emulate classic guitar setups through complex signal processing and which will be providing most of the tonal variation. I’m not privy to how this software does it’s magic, but my assumption is it is primarily using a vocoder/convolution like arrangement multiplying the incoming clean guitar signal with stored waveforms, so it’s my theory that the purer the sound going in, the better these effects are going to work.

Thus, the Ghettocaster will have just one main pickup, I want to put it in the optimal position which emphasises the fundamental tone, and de-emphasises the higher harmonics (particularly the 4th and 6th which contribute the major third and dominant 7th, and everything above the 7th harmonic, which is where all the ‘jazzy’ tones get thrown in). This should give a nice rich pure fundamental, with a side of perfect 5th, which is basically a heavy metal “power chord”.

So where exactly is that ‘magic sweet spot’? Well of course it doesn’t really exist in any practical sense because as soon as you shorten the string by pressing down at a fret it’s going to move about; but for the open string, the response at 1/5th of the scale length (the total distance from the bridge to the nut) looks pretty promising. This will give a good strong dose of the fundamental, 1st, and 3rd harmonics; which are all multiples of the tonic. It will give a strong contribution too from the 2nd harmonic, which provides a perfect 5th. But it is a nodal point of the 4th harmonic, thus effectively eliminating the major 3rd. The harmonics after that up until the 8th harmonic yield either a repeat of the tonic or a perfect 5th. So, if we have the tone control set so that it attenuates the really high frequencies, this should give a fairly fat basic sound.

For the Ghettocaster dimensions, I’m working backward from the Tele style neck (I don’t think it has absolutely authentic Telecaster dimensions, but then I don’t have one to compare against), the distance from the leading edge of the nut slot to the 12th fret is 12 and 3/8ths of an inch, which means the overall scale length needs to be twice that: i.e. 24 and 3/4 of an inch; same as a standard SG I think. The Top Nut is 1 5/8″ across though, which I think is narrower than it should be.

If I butt the heel of the neck up against the back of the neck/first pickup pocket as currently routed in the body, the last few frets will occupy the space where the SG neck pickup would have sat, which will make it a bit less accessible than on a standard SG, but still relatively reachable and I doubt I’ll be doing a great deal of widdling around past the 16th fret anyway. Then if I measure off 4/5ths of the scale length (which is 19 and 3/4 inch if I have it correct), it means the pickup ends up needing to be pretty much neatly up against the leading edge of the second routed pickup pocket, not in the existing pocket of course; that would be too easy, but next to it.

So I need to extend the pocket for it, which will make for rather a large hole; however the custom pick guard will eventually cover it up and having all that space means I’ll be able to experiment with a few placings before committing to a final position. This extended pocket will probably actually make quite a large resonating chamber, and if I mount the pickup on the pick guard itself, then depending on the stifflenss of the material, the top plate will act a bit like the soundboard on an acoustic, and the pickup itself will move with respect to the strings. Quite what effect that will have on the sound (and my little theories above) remains to be seen.

The bridge pickup.

So, the remaining question is; whether to fit a bridge pickup? That is the one that gives that classic twangly Tele sound. For the basic role of the Ghettocaster as I’ve outlined it, it would seem superfluous; however it probably makes sense to add it, because mixing two filtered signals creates much more ‘interesting’ harmonic overtones (like the sound of an acoustic, where all of the overtones are heard), so in case I do ever get to feed the basic guitar into a monster stack of Marshall’s I may want that flexibility. Also, If I do add it, another interesting idea occurs to me, that it might be interesting to route both signals off the guitar unmixed and then combine them later in post processing where it would be possible to get much more creative in deciding exactly which overtones to add, an interesting topic for further investigation at a later date. So it makes sense to do the grunt work for it early on, before the body is finished, and then at least I’ll have the option to mess with the electronics later. On the other hand it means gouging yet another hole out of this nice mahogany. Good news is if I try it; any dodgy handiwork is going to be hidden by the bridge metalwork, but I’m wary of screwing it up.

Decisions, decisions…

Positioning wise, there is already a template slot in the bridge unit; and it seems churlish not to use it. I’m not sure why the bridge pickup is angled the way it is on a Tele; and I can’t be bothered to run all the mathematics to figure out what the harmonics generated would be. If it was good enough for Leo, it’s good enough for me. So that’s the theory anyway, let’s see what happens,

Bring on the twenty tens.

making a guitar

Filed under: Guitar, building, ghettocaster — Sean @ 6:17 pm

Here we are, the last day of 2009; and I started something I’ve wanted to do for a very, very long time. Make my own guitar.

OK, so this is only what we might call the advanced prototype for that guitar. About 5 years ago I was given some very nice lumps of cherry wood from a fallen tree at the festival of wood in Westonbirt arboretum. Those lumps have sat around waiting to have a guitar happen to them all this time (seasoning if anyone asks, OK), however they are just raw lumps of wood, and I don’t have the workshop or skills yet to start completely from scratch, so before I start hacking them up and completely ruin them, I thought I’d better start with something a little easier.

The concept of this guitar has been in my mind for a long time; (pop quiz: What two things do these three guitarists have in common: Frank Zappa, Tony Iommi, and Deke Leonard. Answer – a) They were all powerful musical influences on the young Sean mind, and b) They all played Gibson SG’s when I saw them). I just love that ‘pointy’ body shape, and they sounded pretty good to my ears. Thus, I always wanted a ‘proper’ Gibson SG. However I’ve never gotten round to actually shelling out for one. I did have a nice Epiphone one on loan for about a year though, which scratched the itch briefly.

However I have also always really liked the Telecaster neck and headstock (although I’ve never owned a ‘proper’ one of those either). In fact my own electric guitar is a pretty rare beastie. A black Ibanez custom artist; which is a bit 70’s glam-rock, if you know what I mean. Now if beastie was in pristine condition I could probably trade her in for a genuine SG, but two issues with that. Firstly I’m pretty attached to her, despite her somewhat idiosyncratic looks, and secondly she’s what one might generously call a ‘player’ and not a ‘collector’. Meaning she’s been round the block a few times. Although basically sound she has taken a few dings over the years (mostly before coming into my possession I hasten to add). Beastie has fat little humbuckers, great tone and sustain; but she is also bulky and weighs a lot. So another design consideration is that I wanted something a bit smaller and lighter and the SG shape is nice and light. I also want a fairly natural wood finish, rather than a shiny plastic looking one. I primarily expect to be using this guitar for MIDI input as opposed to running it through a stack of Marshalls (although if I ever get the chance….), so I’ll be using Telecaster type pickups, and possibly just fitting a neck pickup, natural tone is therefore less of an issue here; but I’d still like to have a good basic sound.

Thus, since clearly Fender and Gibson aren’t going to be joining forces any time soon, I present to you Sean’s GhettoCaster (SG – geddit).

Mocking it up in Photoshop quickly (not proud of that neck join!), here is the concept picture I came up with:
Concept picture of custom guitar, SG shape with Telecaster accoutrements

Next problem was finding the time and money to put the thing together. Well, money was sorted by an unexpected little bonus from work just before this Xmas season; and as I generally take a couple of weeks around the holidays, I started doing some internet research. As usual, eBay came up trumps, and I sourced a finished Telecaster neck and unfinished mahogany SG type body. The electronics and gold hardware bits came from an online shop.

Today the last of the bits arrived:
Unfinished SG body of guitar
Neck of guitar

So, with a bit of measuring and marking up, here’s what it looks like roughly placed together:
Neck of guitar

Pleasingly close to my design vision I think. The ‘pickguard’ here is just cut out of a bit of A4 paper, I’ll be ordering a custom pearlescent one when I get a bit closer to the end. The neck seems set a bit too much into the body in the picture. One of the points of the SG shape is access to the upper frets, so I’ll probably move it back a bit in the final design.

Now this project is one step up from a kit, in that there is a genuine design vision going on here. I felt that since this thing is probably gonna end up costing me as much, if not more, than going out and buying a readymade SG or Telecaster clone, there wasn’t any point in making something which is a direct copy, although I’m sure that would have taught me a lot too. Secondly there is a little more involved here than just bolting together off-the-shelf parts, the neck pocket is going to need reshaping to fit the Tele neck, the rear routing for the electronics is the wrong depth and shape; the body is pre-routed for wide Humbuckers, and there is no routing for the bridge Tele pickup. So there seems to be enough of a challenge here to make this a genuine custom project for a first timer. But not so much as starting with a bit of ex tree-trunk.

So, that’s it for part one of the Ghettocaster story. Join me some time in the New Year for the sequel, when we get down to the actual work.

Happy new year,
Sean.

The unnatural musician

Filed under: Guitar, playing — Tags: , — Sean @ 6:54 pm

So, what’s that title about then? You may have heard it said of someone “oh, he/she is so talented, a natural musician”. Well I’ve been hobbling along on the guitar for nigh on three decades now, and I still can’t play a recognizable song all the way through. So, clearly I’m not a ‘natural musician’, hence I must be an ‘UNnatural musician’, since I have persevered with varying levels of effort all this time.

See, I’ve been noodling around with the guitar on and off since I was 16, and now with a major milestone birthday looming in a couple of years (and we aren’t talking 21 here my friends); let’s just say I’m no child prodigy. The problem is I’ve never really practiced properly.

You’ll have heard the phrase “practice makes perfect”, well if that were true I’d be up there noodling around with the likes of Satriani and Vai; however it is in fact, and pardon my french, crap.  The fact is that it is “perfect practice which makes perfect”, a phrase which sounded a bit pretentious to me when I read it (in Versace’s book ‘Welcome to Oz’, which is a truly awesome book on photography btw, sadly out of print now although the new version may be out soon).

The more I think about it though, the more I’m seeing the point. And that point is you need to be disciplined about learning stuff. What you learn needs to be the right stuff, and at the right level of difficulty at the time, for you so that you continue to improve. Practicing is not picking up the guitar for an hour when you feel bored and banging out the same old rubbish over an over again, which is what I have mostly been doing. So over the years I have come to be rather expert at all the things you should not do when learning a musical instrument.

So (and with this sounding dangerously like a NY resolution – something I generally avoid at all costs), I have decided to apply some discipline and actually try to get good in the run up to my 50th (damn, there it is, I said it). The carrot being, that if I succeed, I intend to splash out an obscenely large wad of cash on a reeeally nice guitar for said birthday.

The fun part is, you get to see how well it works out, and if you are in a similar situation (aging tweeneage bedroom rock hero’s of the world unite), you might find something of use for your own situation too.

rock on.

Sean.
