Microtonal guitar music

Igs: Ivor Darreg wrote a couple of preludes for 19-tet guitar, one of which was published in Guitar Player, I think.

Any idea where I can find them?

wouldn't McLaren have copies of Ivor's music since he did eelctronic versions of them all?

It appears that the 12 ET is still hard wired in. John Schneider has one that like this has a slit that runs the whole fret board.

Absolutely brilliant. Not only the instrument, but also
the musicianship, and the fact that these two are together.
I will watch all 24 videos today and/or tomorrow.

Wow! Thanks Oz. That beats even lace-up frets for ease of changing. I'd love to know more about how it works and how it is made. What is the minimum distance a fret can move? Is there a patent? Did Tolgahan engineer the mechanism as well as conceive the idea?

I couldn't find anything about those sorts of questions on the web.

Thank you very much for that, Oz. I passed the link to a couple of colleagues, and (not that I was surprised) one of them - John Schneider - said that he had been in contact with Tolgahan for a number of years, sharing ideas (John is a pretty prominent performer in non-standard-tuning guitar musics, including Partch and Harrison).

Again, thanks.

this version looks like it might be hard to play place a fret close to a 12 ET pitch as the groove appears to stop short of the fret on either side.
The mechanism looks better and maybe quicker, but then again it seems to move in very small steps.
johns i thing is not so fact to change and one can see through the neck which matter little but might bother some.

He playing is quite superb and agree with Carl on that.
The style and sound in a few places reminded me of Rod Poole.

It seems the sonic arts people should also have copies.
One wonders why with all of Ivor's stuff down there, none of it is online~

Yes, you may have posted this before. I wish I had one of these.

Hi Kraig,

There are some images of Tolgahan's adjustable microtonal guitar where there are approximate 12 ET positions having no straight line of fretlets. This makes it clear there is no hard wiring of 12 ET. All frets can be moved.

This seems not that hard to make. In particular a variant in which the
frets have to go all the way across would probably be really easy to
make - just cut a channel or two with a router bit into a standard
fretboard, and then create some frets that have two little pieces
attached to them that fit into the channels, and bam, instant
adjustable ET guitar.

Actually, if you made the two little pieces actually wider than the
channels, and you cut little slots in at predefined spots for
12/17/19/22/31/whatever spots, then you'd have a really easily
adjustable instrument.

This might be a really useful microtonal DIY project. We need more
microtonal DIY instrument projects. This might be the best one yet. If
someone out there would just find a button panel we might have a
second one...

Also, I might pitch the idea to a luthier buddy of mine, but is this
idea patented? It seems like he made it as part of a university
research project. Is the goal for this to be public information, or
for him to mass produce it on his own, or what...? Does anyone know?

The picture i saw the fret started and stopped before the 12 ET ones, is the one saw one continuous groove?

I see now i mistook the perpendicular part that holds the fret as the groove stopping.
That is good since each string has a different thickness really fine tuning would be possible.

As far as the choob. wouldn't it be easy to insert a brace on the inside to prevent it bending over time?

I see that Dave Keenan was able to come up with prelude #1, but I didn't see #2 in any of the replies.

Ivor sent me a copy of #2, but that was many years ago. I'll have to dig through a lot of papers to find it, so it may take a while. I'll make a pdf file of it when I do.

I stand corrected. I checked out Neil Haverstick's message:
/makemicromusic/topicId_23577.html#23577

Prelud #2 is in the Ivor Darreg article on Neil's website:

As a guitarist I'm desperate for an affordable adjustable fret electric guitar or bass. Full width frets would be okay with me, if you tune tonic-fifth-tonic-fifth-tonic-fifth, and tweak the tuning of the fifth strings, many non-EDO microtonal scales are possible. In fact with particular tunings some non-octave scales can be played too.

I was thinking that a low-cost way to achieve this is to start with a guitar (or bass) with a bolt-on neck, remove the neck and ask a luthier to build a non-tapering neck using the tuners from the old neck. Having a neck with a consistent cross-section would make movable frets easier to achieve. Perhaps full-width frets that can be slid to any point and locked into position?

Paul Rubenstein is working on his 'Eleutherotonal Guitar' and may patent the design. I'm very interested to see what he has come up with.

Mat Cooper.

While no instrument might lend it self so easy to EDO's (historically maybe the first instrument to have tempered intervals) I was always struck by what the straight accross fret could provide with even various JI scales.
Rod Poole started with this type of open string tuning ( giving him repeated tetrachords) yet found himself venturing into more adventuresome tunings where he could greatly expand the amount of pitches per octave. Recently i found a 29 tone sclae he worked with based on his 17 frets to the octave.
While i work quite a bit with tunings based on numerical recurrent sequences, the guitar would work well with the actual converged points of these series. This would lead to a simple fluctuation of two sizes as all your MOS scales would be. How something fits under the hand might be a good guide here too. I still have visions of going to Mozambique and giving the Chopi people some guitars tuned to the recurrent series of Meta-Mavila, taken out to either 16 or 23 tones to the Octave. To the Village of Mavila itself would be the best.

Many Just scales are possible with full-width frets without tonic-fifth-tonic-fifth-tonic-fifth open tuning too, as I show here:

Even if the neck is not tapered you can have the strings closer together at the nut than at the saddle. The choob does this. 7 mm spacing at the nut and 10 mm at the saddle. Only the bass string is parallel to the tube axis. On the choob, this automatically gives a progressive lowering of the action towards the treble strings, even when the saddle is constant height.

Thanks for the link to the pdf, this will take a while to digest.
