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.
- PentaMin / PentaEol: Both names indicate that this is a pentatonality. The first name indicates that it is the common root of Phrygian, Aeolian, and Dorian, specifically with the the minor seventh (and no sixth or La), and without second. The second name indicates that this pentatonality corresponds to Aeolian, without the major second or minor sixth. It also corresponds to Phrygian without the minor second or minor sixth, or to Dorian without the major second or major sixth. PentaMin / PentaEol is also known as pentatonic minor.
- Step pattern: Ascending from the fundamental (tonic or Do), a Reach step leads to two consecutive whole steps. Then comes another Reach step. Finally a whole step leads up to the octave.
- Scale intervals: Minor third, quart, quint, and minor seventh.
- Tetra- and trichords: The lower and upper tetra- or trichord are both PentaMin.
- 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 only its right leg. The contrast or South and the West anchor are completely absent.
- Secondary harmonic anchors: Two secondary anchors are present, SE and WN. Both emphasize the fundamental North anchor, the quart, and the East anchor, one more the North, the other the East.
- Piano keyboard reference: PentaMin / PentaEol corresponds to the black keys with D# as fundamental.
