Podcast1024: Boogie Pie by Aaron Krister Johnson

Aaron wrote to describe this piece: "You could say that it uses a 12 of 23-tet scale that Paul Erlich calls 'ripple', and that it is modelled on Conlon Nancarrow's player piano music."

The piece was generated from a MIDI file on his Korg X5DR. 23-tet means that the scale is equally divided into 23 steps, much like the 12-tet scale is divided into 12 steps. This means that there are very notes in common between 12-tet and 23-tet. They are as different as you can get, I suppose. Aaron picked 12 of these tones to use in his piece, and went to work composing. This is the result.

More information about Paul Erlich scale systems can be found here.
