Scale and sound samples
- Clustered or melodic tonality matrix: The octave includes five whole steps and two half steps (or semitones). Either one single or a group of four consecutive whole steps, one and four alternating, separate the two half steps from each other.
- PhrygDorian: The name indicates that the lower tetrachord is Prygian and the upper DorMixolydian. A.k.a. Mixolydian over Phrygian (Mix/Phryg).
- Step pattern: Ascending from the fundamental (tonic or Do), a half step leads to four consecutive whole steps. Then follows the second half step; and a single whole step leads up to the octave.
- Scale intervals: Minor second, minor third, quart, quint, major sixth, and minor seventh.
- Tetrachords: The lower tetrachord is Phrygian and the upper is DorMixolydian.
- Harmonic axes: There are two axes, one horizontal the other tilted, NE-SW and E-W.
- Primary harmonic anchors: The fundamental or North anchor is fully present. The East anchor is incomplete with its head and right leg only. The contrast or South anchor has only its right leg, and the West anchor just its head.
- Secondary harmonic anchors: Two secondary anchors are present, SE and WN. Both strengthen the fundamental North and the East anchor, one more the East and the other more the North, both with emphasis on the quart.
- Minor second and major sixth: Though harmonically least anchored, these two are essential for the distinctive character of this tonality. The minor second emphasizes the regressive, heavy minor or Phrygian character of the lower tetrachord. The major sixth on the other hand contrasts that with a more balanced though not yet fully progressively flavored and still minor upper tetrachord.
