DIY 11 edo stick

I made an instrument today in 11 edo.

All of the details, pictures and demo music are here:

Just the music

Have a great day!!

Nice, it sounds surprisingly good to me considering it has no resonating
chamber and no embedded pickup.

Not to derail the thread, but I'd be very interested in projects involving
recorders, tin whistles, and the like. Are there certain tunings that
suggest themselves for such instruments, either historically or due to the
constraints of the instrument and the player? I suppose one could only
really have a single usable thumbhole, limiting the number of notes - but
I'm not sure, perhaps there are designs I haven't considered. I'm also not
certain about what hole placements and sizes produce the best sound. Also, I
like techniques like overblowing, tremolo(? I don't know what wind players
call it), microtonal trills, etc. Are there designs that esp. facilitate
these? Thanks

I believe Cris talks a lot about that subject in his book.

Ah, that book has shown up many times on web searches. So it is a good one
to use, then - thank you, Chris. Is Mr. Forster on-list? (not that I would
bother him with my questions)

(BTW, what I meant when I incorrectly used the word "tremolo" is a rapid,
repetitive firing of the airflow.)

Hi Chris,

I saw your 11 EDO stick and listened to the piece, very nice.

I had an idea you might be interested in. If you move the saddle certain precise distances closer to the nut you could have lower EDOs (e.g. 10, 9, 8 etc) without refretting. Moving the saddle farther away from the nut you would get higher EDOs (e.g. 12, 13, 14 etc) without refretting.

For 'x' EDO the xth fret should be midway between the nut and the saddle on the lightest string.

John.

You would think so, but the math doesn't actually work that way.
Taking 12-equal and moving the bridge such that the 11th fret bisects
the bridge and nut doesn't actually give you 11-EDO. Work the math out
and you'll see that it doesn't end up right.

Mike,

I did the math and you're right, sorry, I'll be more careful in future.

Thanks for putting me right on this Mike, I've spent years thinking this was possible, luckily I didn't try it out on a guitar.

I thought so too. Then Paul Erlich brought me back to reality. Whoops.

I still think that some tricks like that would have certain applications in Just-intonation.
At least with an aliquote (or subharmonic) scale you can move the bridge anywhere on the divisions.
