The pleasures of listener-sponsored radio

I think it's actually going to happen: On November 10th, the two gentlemen
who come after me in the Sunday evening radio landscape and I are creating a
long meta-program which will air all of LaMonte Young's "The Well Tuned
Piano" in its entirety, from 9:00 PM - ~1:40 AM or so. As it currently
stands, we still need to drop in the regulation FCC station IDs, which we'll
do in between the CDs which comprise the original Gramavision CD release.

It ought to be fun. With that broadcast as an opener, the follow-on program
of other music outside of 12TET will happen a couple of weeks later. Onward.

I use a related comma in my work: the difference between the sum
(product) of a 9/8 and two 5/4s, and a 7/4, or 225/224. The two are
equivalent in tunings where the syntonic comma vanishes, such as 19TET
or 31TET. In 41TET, though, where the 81/80 does _not_ vanish, the
225/224 still vanishes even though the 59049/57344 does not.
