What method of harmonization is Slonimsky using to generate the seven chord progression that belongs to pattern 10? My understanding so far is that the pitches that divide the octave C-F#-C into equal distances are ornamented with 2 notes in between (interpolation) and the first chord C Major outlines SATB, with the ascending form of pattern 10 in the S.
