For piano and electronics: a series of pairs of chords.
For each pair, there is one minute of time between chords, filled by sinetones glissandoing between pitches.
The pitches of all chords are randomly chosen by a PD patch in realtime and played by me on the piano (1-8 notes per chord).
For each chord-pair, the patch will randomly link each note in the first chord with a note in the second chord,
(there will be overlapping links if the the number of notes in the chords are different, but no notes will be left unpaired)
and play 1-minute sinetone glissandos between each linked pitch-pair, at which point I will play the second chord on the piano.
