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.
- HexaLocorReach: The name indicates that this is a hexatonality with its lower half consisting of Core pitches and the upper of a regular Reach setting. Locore tonalities include the three initial of the four corners of the sound temple, i.e. North, East, and South, but not West.
- Step pattern: Ascending from the fundamental (tonic or Do), two consecutive Reach steps lead to two consecutive half steps. Then comes a Reach step followed by a half step that leads up to the octave.
- Scale intervals: Minor third, tritone, quint, minor sixth, and major seventh.
- Tetra- and trichords: The lower trichord is PentaBlue and upper tetrachord is Reach.
- Harmonic axes: There is one axis, which is vertical, N-S.
- Primary harmonic anchors: The fundamental or North anchor is partially present with its head and right leg. The East and the contrasting or South anchor both have their head and left leg only. The West anchor is completely absent.
- Secondary harmonic anchors: There are no secondary anchors.
- Moduation potential: Hexatonalities can facilitate modulations. HexaLocorReach is closely related to other Locore and Core tonalities, especially LoReachUp and ReachUp.
