A diheptatonic scale is a 14-note octave-equivalent scale where both the set of odd-numbered notes and the set of even-numbered notes form a fixed choice of heptatonic scale. Following from this, diheptatonic scales based on a MOS heptatonic scale have a maximum of two sizes for intervals that are an even number of steps.
