During my first year at Princeton, I took private composition lessons with Milton Babbitt (it was his final year teaching). This piece was the result; it used a non-linear transform of a basic pitch series. I think the first movement was intended to "demonstrate the mapping" (yeah...) of the transform, and the second movement did some slow rotations of the transformed set. The first movement was pretty awful, but the second was ok probably because it was slow.
