Like the ultimate "tetris" player, I picked up an art from the old man, who while working for a major "document company" developed the ability to fill every last cubic inch of the trunk of his company car with copier parts in boxes of a hundred different sizes. I've extroplated this *game into retrograding certain melodic fragments to fit into predesignated harmonic structures... not like tonality is/was a goal, but.
