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.
- PentaBluMin: The name indicates that this is a pentatonality consisting of PentaBlu lower pitches along with Phrygian upper pitches.
- Step pattern: Ascending from the fundamental (tonic or Do), a regular Reach step leads to an augmented Reach step. Then follows a half step. Finally two consecutive whole steps lead up to the octave.
- Scale intervals: Minor third, quint, minor sixth, and minor seventh.
- Tetra- and trichords: The lower trichord is PentaBlu and the upper tetrachord is PhrygAeolian.
- Harmonic axes: There is no axis.
- Primary harmonic anchors: The fundamental or North anchor is partially present with its head and right leg, the East anchor fully present. The South or contrast anchor and the West anchor are completely absent.
- Secondary harmonic anchors: There is no secondary anchor.
- Penta- to hepta- and hexatonality correlation: PentaBluMin is equivalent to HexaBluMin without quart, HexaLocorMin without tritone, or to Phrygian, LoReachUpMin, Aeolian, ReachUpMin, or BlueMin without second and quart or tritone. And it is closely related to PentaNaMin, PentaBluReach, and PentaBluMix.
