This piece travels from Am9 to Dm9 through the 35 possible different 4-note chords that can be formed from the notes in both (i.e. the C major scale spread over two octaves), changing only one note each time. After trying various mathematical ways to generate a sequence that met these constraints, I ended up resorting to a brute force algorithm picking pairs at random.

I used SonicPi to play the sequence using the 4-voice Minilogue xd. The music is accompanied by sounds from a field recording I made along the Thames Path in Rotherhithe a few weeks ago.

The code used to generate this is here: https://gist.github.com/threedaymonk/de5896d76dd456fef47f3ab91a13e8e5
