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.
- HexaPhryg: The name indicates that this hexatonality corresponds to Phrygian with the minor seventh but no sixth.
- Step pattern: Ascending from the fundamental (tonic or Do), a half step leads to a trio of consecutive whole steps. Then comes a Reach step. Finally a whole step leads up to the octave.
- Scale intervals: Minor second, minor third, quart, quint, and minor seventh.
- Tetra- and trichords: The lower tetrachord is Phrygian; and the upper trichord is PentaMin.
- Harmonic axes: There is one axis, which is tilted, NE-SW.
- Primary harmonic anchors: The fundamental or North anchor is fully present. The East anchor is partial, with its head and right leg only, and the contrasting or South anchor with only its right leg. The West anchor is completely absent.
- Secondary harmonic anchors: Two secondary anchors are present, SE and WN. Both emphasize the fundamental North anchor, the quart, and the East anchor.
- Moduation potential: Hexatonalities can facilitate modulations. HexaPhryg may for example help bridge between Phrygian, PhrygDorian, PhrygBlue, PentaMin/PentaEol, etc.
