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.
- HexaMix: The name indicates that this hexatonality corresponds to Mixolydian with the minor seventh but no sixth. It is the equivalent of Mixolydian without its major sixth.
- Step pattern: Ascending from the fundamental (tonic or Do), two consecutive whole steps lead to a half step. Then comes a whole step and a Reach step. Finally a whole step leads up to the octave.
- Scale intervals: Major second, major third, quart, quint, and minor seventh.
- Tetra- and trichords: The lower tetrachord is MixolydIonian, and the upper trichord is PentaMin.
- Harmonic axes: There is no axis.
- Primary harmonic anchors: The fundamental or North anchor is fully present. The West anchor is partial with both legs but no head, and the East anchor with only its right leg. The contrasting or South anchor is completely absent.
- Secondary harmonic anchors: Two secondary anchors are present, SE and SW. Both emphasize the fundamental or North anchor, one with focus on the quart, the other on the quint. Further, to a lesser degree, one strengthens the East and the other the West anchor.
- Moduation potential: Hexatonalities can facilitate modulations. HexaMix may for example help bridge between Mixolydian, IonAeolian, PentaMix/PentaDor, etc.
