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.
- PentaMixLa / PentaMixolyd: Both names indicate that this is a pentatonality and express its correspondance to Mixolydian. The first name underlines that this pentatonality includes the major sixth (La and Last harmonic in the series) but no seventh. It is the common root of Dorian, Mixolydian, and Ionian. The second name indicates that this pentatonality corresponds to Mixolydian, without the major third or minor seventh. It also corresponds to Dorian without the minor third or minor seventh, or to Ionian without the major third or major seventh. PentaMixLa / PentaMixolyd is also known as blues major.
- Step pattern: Ascending from the fundamental (tonic or Do), a whole step leads to a Reach step. Then come two consecutive whole steps. Finally a Reach step leads up to the octave.
- Scale intervals: Major second, quart, quint, and major sixth.
- Tetra- and trichords: The lower tetra- or trichord is PentaMix and the upper PentaMaj.
- Harmonic axes: There is no axis.
- Primary harmonic anchors: The fundamental or North anchor is fully present. The West anchor is partial, with its head and only its left leg. The East and the contrast or South anchor are completely absent.
- Secondary harmonic anchors: Two secondary anchors are present, EN and SW. Both emphasize the fundamental North anchor with the quint, and the West anchor, one more the North, the other more the West.
- Piano keyboard reference: PentaMixLa / PentaMixolyd corresponds to the black keys with C# as fundamental.
