 Carrillo used many intervals, although mainly in multiples of 4 such as 16, 32, and 64 so that between each of the whole tones, 16, 32, or 64 additional notes were created.Carrillo called these intervals 16hs of a tone, 32nds of a tone, and 64ths of a tone, respectively.As a result, C would be labeled 0, D flat would be labeled 8, D would be labeled 16, E flat would be labeled 24, E would be labeled 32, etc., for 16ths of a tone.
