I've been playing guitars with frets spaced by about a third of a tone rather
than the usual semitones, so about 68 cents rather than 100 cents. Also I've
been tuning the strings in minor thirds. I really enjoy playing tunings like
this; they seem very intuitive plus have some nice properties which I'll try
and write something about.

Also I must write something about Harry Partch's 'Genesis of a Music', that
book certainly means a lot to me!
