SubjectNotes on notes on the plane
I've posted at http://ansuz.sooke.bc.ca/entry/289 a set of notes on my
piece "Black Swan Suite"; links there to the document in PDF format and
the recording on Soundcloud.

The music is generated by tracking the motion of "hunters" as they move
along the vertices and edges of a nonperiodic tiling of the plane, seeking
a point that moves according to a fractal random walk.  The 360-degree
circle of directions a hunter can move is mapped onto the octave.
Different tilings (used in different movements of the piece) contain
different sets of edge slopes, which set the pitch classes and resulting
intervals that will appear.  Two of the five movements end up being in
12edo; one in 10edo (based on Penrose tiles, with fivefold symmetry); one
would be in 6edo (whole tone scale) but is retuned to an unequal six-part
division of the octave; and the final movement is generated by a pinwheel
tiling with an infinite number of distinct edge slopes, generating in
principle a scale-less composition.

The rendering was all done with Csound, so I hope my plugging it will be
welcome here on the list; but in fact the document I just posted mostly
describes the theory behind the score, with very little on Csound.
