Probably almost impossible to adapt written works 'backwards' into a visualization but it might be fun to have different bars represent different notes and have the balls split for chords.
Having N paddles would be cool as well, perhaps with a cost for paddles getting too close (to avoid trivialities), and optimizing which note each paddle represents/beats, maybe imposing a cost on drastic pitch changes so that each specializes in a pitch range.
