«Beatboxing and Bach» by aahrens

on 24 Oct'18 20:10 in bachinventionclassical

Taking inspiration from "Switched-On Bach", this is a supercollider rendition of Invention No. 13 in A Minor.

The melody is held in Pbinds, and I modified Bruno's percussion SynthDefs to sound like a person beatboxing.
