Years ago, when I was first learning how to use Ableton, I created all of these 2-voice compositions using very harsh square waves. Most of them never left Ableton and remain in my “Sketches” folder.
Recently though, I’ve dusted a few of them off to see if I can make them more interesting as piano compositions + sound design. This is one of the more minimalist/ambient ones. It’s mostly stagnant, but has some development in reverb, delays, and rhythmic interplay between the right and left hands.
