…really loved this weeks prompt, and I had a day off to participate…
I just knew I had to try out a 12 tone row and 11 intervals - so I used the Mother Chord row used by, among others, Alban Berg in his Lyric Suite - the notes are F, E, C, A, G, D, A♭, D♭, E♭, G♭, B♭, C♭.
I had an idea of using a Glockenspiel to imitate the tradition of waiting music - I ended up with a preset in Ableton that I liked. I the wrote the notes in the piano roll. I then had Ableton going through the motions to form the 4 possibilities of retrograde/inversions to form the “melody”.
The “bass line” is an inversion of the original row quad-doubled in time. I then moved individual notes to form movement through a rhythm.
The tempo is 66 BPM - since I learned that the sum of numbers 1 through 11 equals 66. I “looped” the piece 6 times before uploading it to Soundcloud.
