JFugue27. Smoke On the Water by Deep Purple.

This program uses the Transpose class and the Parse Listener.

This plays Smoke On the Water by Deep Purple. For voice 1, the pattern of voice0 is lowered by octave and we start at beat 8. One beat is a quarter note. Both voice 0 and voice 1 are the same instument (OVERDRIVEN_GUITAR). We also have ELECTRIC_BASS_FINGER and percussion (ACOUSTIC_SNARE).
