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.
- PentaMix / PentaDor: Both names indicate that this is a pentatonality. The first name points out that It corresponds to Mixolydian without major sixth (or La) but with the minor seventh. This pentatonality is the common root of Mixolydian, Dorian, and Aeolian. The second name indicates that it corresponds to Dorian, without minor third or major sixth. Further, it corresponds to Mixolydian without major sixth or major third, and to Aeolian without minor third or minor sixth. PentaMix / PentaDor is also known as Egyptian scale.
- Step pattern: Ascending from the fundamental (tonic or Do), a whole step leads to a Reach step. Then comes a whole step and another Reach step. Finally a whole step leads up to the octave.
- Scale intervals: Major second, quart, quint, and minor seventh.
- Tetra- and trichords: The lower tetra- or trichord is PentaMix and the upper PentaMin.
- Harmonic axes: There is no axis.
- Primary harmonic anchors: The fundamental or North anchor is fully present. The East and West anchors are partial, with no head and only one leg each, the right one for the East and the left one for the West. The contrast or South anchor is completely absent.
- Secondary harmonic anchors: Two secondary anchors are present, SE and SW. Both emphasize the fundamental North anchor, one the quart, the other the quint; and to a lesser degree, one gives some strength to the partial East, the other to the West anchor.
- Piano keyboard reference: PentaMix / PentaDor corresponds to the black keys with G# as fundamental.
