A tough assignment

Tonight there's a strange and difficult assignment. Make a minute of music out of some extraordinarily basic building blocks. The following notes:
C
D
Eb
each note played a maximum of 3 times, in any octave, for any length you wish. Have them overlap if you want, or run them through all sorts of effects. No percussion though - just the notes themselves (unless you can fake some sort of percussion by using the notes themselves.

So we're each trying to make a 1 minute song out of 3 notes repeated 3 times each. Nothing else.
