Scale and sound samples
- Diatonic tonality matrix: The octave includes five whole steps and two half steps (or semitones). Either two or three consecutive whole steps, a pair and a trio, alternate in separating the two individual half steps from each other.
- Step pattern: Ascending from the fundamental (tonic or Do), Mixolydian begins with two whole steps, followed by a half step. Then comes the pair of whole steps and the second half step, before the remaining whole step leads up to the the octave, which is embedded in the trio of whole steps.
- Scale intervals: Major second, major third, quart, quint, major sixth, and minor seventh.
- Penta- and tetrachords: The lower pentachord is MixolydIonian, and the upper tetrachord is DorMixolydian.
- Harmonic axes: There is one axis, ES-WN.
- Primary harmonic anchors: The fundamental or North and the West anchor are both fully present. The East anchor is incomplete and contributes just one leg, its right one. The contrast or South anchor is completely absent.
- Secondary harmonic anchors: Three secondary anchors are present: EN, SE, and SW. All three of them strengthen the fundamental North anchor — two with focus on the quint and one on the quart. Two of them give some more weight to the West anchor, and one to a lesser degree to the partial East anchor.
- The minor seventh: Harmonically least anchored, it makes the upper tetrachord minor. This stands in contrast to the full presence of the major or West anchor and provides the distinctly Mixolydian remnant of a regressive touch in an otherwise progressively flavored frame.
- Piano keyboard reference: Mixolydian corresponds to the white keys with G as fundamental.
