Any MOS may be constructed from 1L 1s using two "golden operations": chromaticizing (taking the soft child of the MOS) and inverting (inverting the number of large and small steps). In effect, this makes taking the hard child "cost" 2 instead of 1. This table shows the number of such operations required to reach any MOS under 15 notes (that MOS' "height"): The total number of MOSes at each height corresponds to the Fibonacci sequence. | Any MOS may be constructed from 1L 1s using two "golden operations": chromaticizing (taking the soft child of the MOS, thus continuing the golden sequence) and inverting (inverting the number of large and small steps, switching to a new golden sequence).
