Katikaze: Study in Single Notesfor piano solo[0:51]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 just preceding it except that the now omitted "old" first member, instead of re-appearing at the new row's end, popped 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 have made one global adjustment: at each "new" (surprise) pitch, octave registration is reset to that note's position in the immediately preceding measure.
The result is meant as a study in rapid (dotted half = 126?) single-note playing, especially involving irregular hand-swaps in extreme range. It might best be programmed as an immediate sequel to Midi-Studies on my Surname. I should note that damper pedal release is to occur at -- not after -- the last note of each bar.
Originally named Whirly, this work now honors my daughter's cat, who notably survived a flight from his 3rd-story Manhattan apartment window.
