Harmonic Interval Sets

These sets consist of 2 notes on the 12-note chromatic scale, dependent on the semi-tonal distance between the 2 notes. Semi-tonal means that the notes are consistent in their tuning and perfect in pitch with each other, instead of micro-tonal intervals, which are much closer and smaller than the 12-note scale.
