From the Tribonacci summation sequence mod 12, a cycle of 104 members, I extracted non-repeating series, scanning forward from each member in turn. The output list showed each row resembling a first rotation of the row immediately before it except that the now omitted "old" first member, instead of re-appearing at the new row's end, cropped up in it somewhere -- as if "anywhere" -- else, in a juggle of predictability and surprise.

Plotting this artifact intervallically, even after compression to signed interval classes, commandeered a range of several keyboards. To constrain it then, I made one global adjustment: at each "new" (surprise) note, octave registration is reset to that note's position in the preceding measure.


The piece is meant as a study in rapid single-note playing, especially involving irregular hand-swaps in extreme range. I suggest playing it as a sequel to Midi-Studies on my Surname. Pedal release is to occur at -- not after -- the last note of each bar.


Originally called "Whirly". this work now honors my daughter's cat, who notably survived a flight from his 3rd-story Manhattan apartment window.
