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.
- BlueMin: The name indicates that the Reach step is in the lower tetrachord and that the upper tetrachord is PhrygAeolian.
- Step pattern: Ascending from the fundamental (tonic or Do), a Reach step leads to a whole step followed by three consecutive half steps. Then two whole steps lead up to the octave.
- Scale intervals: Minor third, quart, tritone, quint, minor sixth, and minor seventh.
- Penta- and tetrachords: The lower pentachord is Blue. The upper tetrachord is PhrygAeolian.
- Harmonic axes: There in one axis that is vertical, N-S.
- Primary harmonic anchors: The fundamental or North and the East anchors are fully present. The contrast or South anchor has only its head and no legs. The West anchor is completely absent.
- Secondary harmonic anchors: Two secondary anchors are present, SE and WN. Both emphasize the fundamental or North and the East anchors and the quart, one more the North the other the East.
- Three consecutive half steps: The co-existence of the quart, tritone, quint, and minor sixth.
