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.
- LoloReach: The name indicates that the lower tetrachord is the lowest possible or Lolo version of Reach, and the absence of a further indication points out that the upper is regular Reach.
- Step pattern: Ascending from the fundamental (tonic or Do), a Reach step leads to two consecutive half steps. Then comes a whole step, a half step, and a Reach step. Finally a half step leads up to the octave.
- Scale intervals: Augmented second / minor third, major third, quart, quint, minor sixth, and major seventh.
- Tetrachords: The lower tetrachord is Lolo and the upper is Reach.
- Harmonic axes: There is one axis that is tilted: SE-NW.
- Primary harmonic anchors: The fundamental or North anchor is fully present. The East anchor is partial with its head and left leg only. The contrast or South and the West anchors each have only one leg, the South the left and the West the right one.
- Secondary harmonic anchors: There are no secondary anchors.
- LoloReach offers an enticing combination of the bluesy initial or lowest possible Reach step with another, regular Reach step in the upper tetrachord.
