Scale and sound samples
- Reach or harmonic tonality matrix: The octave includes one or exceptionally two (double harmonic) Reach steps (augmented seconds) framed by half steps (or semitones) or exceptionally by a whole and a half step. There are either three whole steps or exceptionally just one. If three of them, they are in most cases either a pair and a single one separated by the third half step, or a trio framed by half steps. Exceptionally though all three whole steps are singles. When a trio of consecutive whole steps, they are preceded or followed by two consecutive half steps. The total number of half steps is three, or exceptionally four with two (double harmonic) Reach steps.
- ReachUpMin: The name indicates that the Reach step in the lower tetrachord is shifted up and that the upper tetrachord has a PhrygAeolian tonal character.
- Step pattern: Ascending from the fundamental (tonic or Do), a whole step leads to a half step followed by a Reach step. Then come two consecutive half steps and finally a pair of two consecutive whole steps that lead up to the octave.
- Scale intervals: Major second, minor third, tritone, quint, minor sixth, and minor seventh.
- Penta- and tetrachords: The lower pentachord is ReachUp, the upper tetrachord is PhrygAeolian.
- Harmonic axes: There are two axes, one vertical, the other tilted, S-N and EN-WS.
- Primary harmonic anchors: The fundamental or North anchor has its head and only the right leg. The East anchor is fully present. The contrast or South anchor has its head and no legs; and the West anchor is present with only its left leg.
- Secondary harmonic anchors: One secondary anchor is present, SW. It strengthens the fundamental North anchor, with emphasis on the quint, and to a lesser degree the otherwise only minimally present, partial West anchor.
- Tritone: In this multi-flavored tonality, the tritone is most essential in that it helps form the elevated Reach step and the vertical axis. Further, it expands the otherwise very pronounced regressive or minor flavored tendency of this tonality.
