Scale and sound samples
- Tritone or blues tonality matrix: The octave includes the tritone plus for a heptatonality one, for a hexatonality two, and for a pentatonality three Reach steps (augmented seconds). These take off from the fundamental or from the quint. They are not framed by half steps (or semitones), of which there are three for hepta-, two for hexa-, and one for pentatonalities. When more than one of them, then some are consecutive.
- PhrygBlue: The name indicates that the lower tetrachord is Phrygian, and that the Reach step is in the upper tetrachord.
- Step pattern: Ascending from the fundamental (tonic or Do), a half step leads to two consecutive whole steps, followed by two consecutive half steps. Then there is a Reach step; and finally a whole step leads up to the octave.
- Scale intervals: Minor second, minor third, quart, tritone, quint, and minor seventh.
- Tetrachords: The lower tetrachord is Phrygian (reduced), the upper is Blue.
- Harmonic axes: There are two axes, one vertical the other tilted, N-S and NE-SW.
- Primary harmonic anchors: The fundamental or North anchor is fully present. The East and contrast or South anchor are both partial, each with their head and their right leg only. The West anchor is completely absent.
- Secondary harmonic anchors: Two secondary anchors are present, SE and WN. They both emphasize the fundamental North anchor, the quart, and the partial East anchor, one more the North and the other more the East.
- Regressive but still also progressive: The pitch distribution presents a homogeneously regressive and heavy minor tonal flavor, akin to both Locrian and Phrygian, but remains anchored in both, quart and quint, the regressive and progressive.
