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. A clustered pentatonality has two consecutive Reach steps and three consecutive whole steps. Some further basic pentatonalities contain three Reach steps, at least two of them consecutive. And extended pentatonalities include a double whole step plus one or two Reach steps.
- 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.
