I revised this score and added a sound file below.
Here's a bitonal composition of a rather different sort. The melody is in parallel 3rds, creating the keys of Eb & G in the melody in the A section (1st 8mm). The melody is in D in the 2nd 8, while the harmony is in Eb (the primary key) throughout. In addition, this piece is "metrically-challenged."
Click below for sound; sorry for the midi rendering.
