COMPOSITION NOTES

This student work, written at Yale in 1971 for Alexander Goehr's seminar, was
my first experiment with synthetic modes. I built a heptatonic scale having two
augmented 2nds, keyboard symmetry, and a leading tone at the "wrong" end.
Respelled here for convenience:

C   C#   D#   E   G   G#   A   (C)   .

I decided to use as well, separately or in combination, its pentatonic compliment,

A#   B   D   F   Gb   .

Variations offered a likely compositional way to proceed, and Beethoven's 32
in C-Minor, which I was playing at the time, inspired a dare to make my theme
short.
