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.
- PentaNaMaj: The name indicates that this is a pentatonality with the first primary Na(tural) harmonics or overtones in the lower trichord and the upper tetrachord being IonLydian.
- Step pattern: Ascending from the fundamental (tonic or Do), an augmented Reach step spanning over four semitones leads to a regular Reach step. Then follow two consecutive whole steps. And Finally a half step leads up to the octave.
- Scale intervals: Major third, quint, major sixth, and major seventh.
- Tetra- and trichords: The lower trichord is TetraNa and the upper tetrachord is IonLydian.
- Harmonic axes: There is no axis.
- Primary harmonic anchors: The fundamental or North as well as the West anchors are both partially present with thier head and right leg. The contrast or South anchor has only its left leg. The East anchor is completely absent.
- Secondary harmonic anchors: There is one secondary anchor, ES. It emphasizes the West and to a lesser degree the contrast or South anchor.
- Penta- to hepta- and hexatonality correlation: PentaNaMaj is equivalent to HexaProMaj without second or to ReachMaj, Ionian, ReachNaMaj, or Lydian without second and quart or tritone. Obviously PentaNaMaj is closely related to PentaNa / PentaPro and PentaNaMix.
