Scale and sound samples
- Pentatonality matrix: The octave of a regular pentatonality includes two Reach steps, three whole steps, and no half step (or semitone). One or two consecutive whole steps frame and separate the two Reach steps. An extra pentatonality can be with two consecutive Reach steps and three consecutive whole steps. Or it can be with three Reach steps, at least two of them consecutive, plus one whole and one half step. Or further, it can be with a double whole step, one or two Reach steps, one or two whole steps, plus one or no half step.
- PentaCor: The name indicates that this is a pentatonic version of a Core tonality. It is cross-anchored and includes all four corners of the sound temple.
- Step pattern: Ascending from the fundamental (tonic or Do), two consecutive Reach steps lead to a half step. Then comes a whole step. Finally another Reach step leads up to the octave.
- Scale intervals: Minor third, tritone, quint, and major sixth.
- Tetra- and trichords: The lower tetra- or trichord is PentaBlue and the upper is PentaMaj.
- Harmonic axes: There are two axes, which are vertical and horizontal, N-S and E-W.
- Primary harmonic anchors: All four primary anchors are present with their heads only, except for the fundamental or North anchor that in addition to its head also has its right leg.
- Secondary harmonic anchors: There are no secondary anchors.
- All four corners of the sound temple plus the quint that strengthens the fundamental and anchors in a more common sense of harmony.
- Penta- to hepta- and hexatonality correlation: PentaCor is equivalent to HexaCorMix and HexaCorMaj without a seventh. PentaCor is closely related to other cross-anchored tonalities like ReachUpMix, ReachUpMaj, LoReachUpMix and BlueMix.
