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.
- HexaBluReach: The name indicates that this hexatonality has a blue lower character or the minor third without second plus a regular upper Reach step. It is the equivalent of PhrygReach without its minor second or MinReach without its major second.
- Step pattern: Ascending from the fundamental (tonic or Do), a Reach step leads to a pair of consecutive whole steps. Then comes a half step and another Reach step. Finally a half step leads up to the octave.
- Scale intervals: Minor third, quart, quint, minor sixth, and major seventh.
- Tetra- and trichords: The lower tetrachord is PentaMin, and the upper is harmonic or Reach.
- Harmonic axes: There is no axis.
- Primary harmonic anchors: The fundamental or North anchor is fully present. The East anchor is partial, with its head and left leg, and the contrasting or South anchor with its left leg only. The West anchor is completely absent.
- Secondary harmonic anchors: No secondary anchors are present.
- Moduation potential: Hexatonalities can facilitate modulations. HexaBluReach may for example help bridge between PhrygReach, MinReach, etc.
