Getting Started in Microtonality

Welcome aboard the world of unusual musical tunings!

> How can I tune my MIDI keyboard to something other than 100 cent intervals?

Unfortunately, there are nearly as many answers to that question as there are
keyboards themselves!

First of all, you might want to start with John Loffink's MIDI-instrument web
pages, to see which
ones have that ability. It's at: http://home.att.net/~microtonal/

Once you choose a keyboard that has that ability, then we can answer that
question in more detail.

> Where can I get a neck for a guitar that's fretted with different spacing...
19 per octave, etc.?

Well, it's really not all that difficult to refret a guitar yourself, as long as
you have a typical
handyman-like skill and have a Luthier's Merchantile catalog (800) 477-4437),
and know how
to perform a few pretty simple calculations. I suggest you start with a cheapie
guitar that you
can "throw away" (more likely figuratively speaking than literally) as a
first-try learning
experience. That is, if you're into $1000 guitars, I suggest doing a cheaper
one first.
