Musical notes and their arrangement in a score are reminiscent of sequences of numbers. Harmony in particular can be analysed by the computer because it is mostly defined by intervals between neighboring notes, which correspond to intervals between numbers. The picture shows the interface to program Li wrote during Summer Institute, 1993 which graphically depicts the harmonies in a piece of music as it is playing. The algorithm is described in the Summer Institute 1993 reports.
