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
