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.
- PentaBluNaLa: The name indicates that this is a pentatonality based on the first few Na(tural) harmonics with the addition of the Blu(esy) minor third in the lower tetrachord. The syllable La indicates the presence of the major sixth.
- Step pattern: Ascending from the fundamental (tonic or Do), a Reach step leads to a half step. Then comes another Reach step and a whole step. Finally a third Reach step leads up to the octave.
- Scale intervals: Augmented second / minor third, major third, quint, and major sixth.
- Tetrachords: The lower tetrachord is PentaBluNa, while the upper is PentaMaj.
- Harmonic axes: There is one axis that is horizontal: E-W.
- Primary harmonic anchors: The fundamental or North and the West anchors are both partially present with their heads and right legs only. The East anchor is partial with only its head, while the contrast or South anchor is completely absent.
- Secondary harmonic anchors: There are no secondary anchors.
- Penta- to hepta- and hexatonality correlation: PentaBluNaLa is somewhat related to LoloReachLyd/CorMaj, LoloReachMaj, LoloReachMix, CorMix, derivatives HexaCor and LoCor, plus obviously PentaBluNa.
