A new part of the network score series; this time for between two and four pianos. More open than the string quartet version. More silences.

Most likely of interest to no-one, I’ve knocked up a little spreadsheet to help calculate string harmonics on a prepared piano.
If you set the partial number, it gives you the sounding pitch. If you calibrate the string length, it gives you the node location.

I’m currently working on a composition which uses the Collatz Conjecture (or Hailstone Numbers) as source data in a piece for solo Disklavier Piano. Below is a screenshot from a (currently too messy to post) Processing script I wrote to get a better idea of the behavior of these numbers.
The main inspiration behind the piece is György Ligeti’s Piano Etude no.1: Disordre. I love the frenetic pace, and the algorithmically derived recursion of the piece, but with the Collatz project I’m toying with the concept of softening the aggressive/human element of that speed (the Disklavier can play very fast with a ‘softer’ touch/velocity), in a falling ‘hailstone’ pattern.
