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.
- HexaMinLa: The name indicates that this hexatonality corresponds to AeolDorian with the major sixth but no seventh. It is the equivalent of Dorian without its minor seventh.
- Step pattern: Ascending from the fundamental (tonic or Do), a whole step leads to a half step. Then comes a trio of consecutive whole steps. Finally a Reach step leads up to the octave.
- Scale intervals: Major second, minor third, quart, quint, and major sixth.
- Tetra- and trichords: The lower tetrachord is AeolDorian, and the upper trichord is PentaMaj.
- Harmonic axes: There is one axis, which is horizontal, E-W.
- Primary harmonic anchors: The fundamental or North anchor is fully present. The West anchor is partial with its head and only its left leg, and the East anchor with only its head and no legs. The contrasting or South anchor is completely absent.
- Secondary harmonic anchors: Two secondary anchors are present, EN and SW. Both emphasize the fundamental or North anchor, with focus on the quint, and the West anchor, one more the North, the other more the West.
- Moduation potential: Hexatonalities can facilitate modulations. HexaMinLa may for example help bridge between Dorian, DorIonian, ReachUpMix, ReachUpMaj, PentaMinLa/PentaBal, PentaMixLa/PentaMixolyd, etc.
