 Julián Carrillo started dividing whole tones (major seconds) into 16 intervals, but he did not stop there.Through experiments, Carrillo noticed that he could divide the string into an infinite number of intervals, or into as many intervals as it is physically possible.Carrillo created intervals of 3 (), 4 (), 5 (), 16 (), 32 (), 64 (), and 128 () tones within a major second, leaving the formula to create more, if desired.
