The numbers correspond to drawing from his three realms: Tritone
Progression, affiliated with S an MP's 1 thru 180. Ditone progression:
181 thru 391 and Sesquitone pogression: 392 thru 568. Page "V" (Of
introduction) displays examples in the three respective realms. In
example V, you have the tritone C and F#. {Circled numbers, as realms
must be utilized in conjunction with the pattern numbers, even though
many will be the same inter-realm}This correlates with his F#7 and C7
triads (5th omitted). The G and Db, also a tritone are added tones,
each a P5 above each principle tone (of the initial tritone). He
considers the additional tritone (G and Db), "melodic elements" of
which he adds to C and F#. Leaving the 5th out of the master chords,
frees the ear up to accept bitonality. I have no problem with pattern
53 fitting the masterchords. In Jazz, we will voice much hipper than
that and still leave the fifth out. Of course,, youm are hip to this.
I am just trying to answer you as best I can at the moment.
The next double barline example, Pattern #186 reveals two sets of
augmented triads. You already know that in the land of "Augie
Augment", major 7ths and dom 7ths entertain harmonic coalition. This
sounds like a plausible pattern/line to me, if we keep this in mind.
The next double barline example, pattern # 393 reveals quite obviously
two diminished chords juxtaposed a la double-diminished. The
masterchords correspond accordingly. But I wouldn't try this stuff on
an accordion.
Is how I see it. He is demonstarting bi-tonality and the idea of
melodic patterns mixed in with known and not so known scales (hybrids)
is "key."
