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.
