A bit of noise for for the 2010 “30 Days of Creativity” project. I started with a MIDI file of J. S. Bach’s Two Part Invention in F Major, BWV779. Then I replaced the pitch in each note on event with the pitch class from the 19th subsequent note on event — but in the same octave as the original pitch. (19 is the number of letters in “Johann Sebastian Bach”.) So it’s the same pitch classes as Bach’s, same octaves, and same rhythms — except that the pitch classes are time shifted. The result sounds like… well, not what Bach had in mind. The rough version in the YouTube video is a computer rendering, as will be the somewhat nicer MP3 version to come.
