Scale and sound samples
- Hexatonality matrix: The octave generally includes one Reach step, four whole steps, and a single half step (or semitone). Two or three (or exceptionally all four) whole steps appear consecutively. Thus there are two pairs of consecutive whole steps or a trio plus a single. They are framed by the half step on one side and the Reach step on the other. Exceptionally there can be two Reach, two whole, and two half steps. Plus there is one case with three Reach and three half steps.
- HexaProMix: The name indicates that this is a hexa- and Pro tonality with the upper tetrachord DorMixolydian. As Pro tonality, the lower tetra- or trichord is major without the regressive quart. The identifier Pro stands for progressive.
- Step pattern: Ascending from the fundamental (tonic or Do), two consecutive whole steps lead to a Reach step. Then follows a whole step and a half step. Finally a whole steps leads up to the octave.
- Scale intervals: Major second, major third, quint, major sixth, and minor seventh.
- Tetra- and trichords: The lower tetra- or trichord is PentaMaj and the upper is DorMixolydian.
- Harmonic axes: There is one axis, ES-WN.
- Primary harmonic anchors: The fundamental or North anchor is partially present, with its head and right leg. The West anchor is fully present, while the East anchor has only its right leg. The contrast or South anchor is completely absent.
- Secondary harmonic anchors: Two secondary anchors are present, EN and SW. Both emphasize the fundamental North anchor with the quint as well as the West anchor, one more the North, the other more the West.
- Hexa- to Hepta- and Pentatonality correlation: HexaProMix is equivalent to Mixolydian without quart, to PentaProLa/PentaIon with minor seventh, or PentaPro/PentaNa with major sixth.
