You can play ABACABA on an instrument. The letters of the name describe the notes. The melody is in the key of A-minor and it sounds quite nice.
Here’s a few different arrangements…
Listen to a fully orchestrated version here:
Abacaba patterns are embedded not only as notes, but in the rhythms, stereo effects and more. (Download the fully orchestrated version as an mp3.)
Download sheet music for version 1 so you can play it yourself on piano.
Here’s a marble machine that plays the Abacaba pattern. The flippers are counting in binary from 0 to 127 as it plays from an A to an A one octave higher before repeating.
