This music is melodically and harmonically based entirely on equal octave divisions: the tritone, the augmented chord, the diminished 7th, the whole-tone scale, and the 12 semitones.

Story behind the song
Scales and chords are made by paralleling these divisions, for example, with the diminished 7th chord division, the octatonic scale (either step/half-step, or half-step/step; or, with the augmented chord division, with say, C C-sharp E F G-sharp A C', or with the whole-tone scale, or with C D-sharp E G G-sharp B C'.
As for the 12 semitone division, I leave myself free to use conventional diatonic melody (but with parallelism for chord changes), or I'll use parallel fourths and fifths. With the tritone division, I tend to do such things as, say, B C C-sharp F F-sharp G; apart from that, I'd just get the diminished 7th and whole-tone scale divisions.
