LydAeolian / HeptaNa or Lydian dominant ♭6 — a prime Na tonality and clustered heptatonality
Harmonic visuals
Scale and sound samples
You may enjoy a sound sample or tonality loop as sound mantra for contemplation or meditation, for upliftment and focusing, or simply as soothing background sound for relaxation and regeneration.
Characteristics
- 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. In super-clustered tonalities all five whole steps and also the two half steps are consecutive.
- LydAeolian or HeptaNa: The first name indicates that the lower tetrachord is Lydian and the upper PhrygAeolian. The second name indicates that this is the full primary Na(tural harmonics) heptatonality. A.k.a. minor over Lydian (Min/Lyd).
- Step pattern: Ascending from the fundamental (tonic or Do), three consecutive whole steps lead to two consecutive half steps. Then two consecutive whole steps lead up to the octave.
- Scale intervals: Major second, major third, tritone, quint, minor sixth, and minor seventh.
- Penta- and tetrachords: The lower pentachord is Lydian and the upper tetrachord is PhrygAeolian.
- Harmonic axes: There are three axes evenly spread with one vertical, N-S, EN-WS, and ES-WN.
- Primary harmonic anchors: The fundamental or North anchor is partially present with its head and right leg. Also partially present are the East and West anchors, each with both their legs but no head, and the contrast or South anchor with its head only and no legs.
- Secondary harmonic anchors: There is one secondary anchor, SW. It strengthens the fundamental or North anchor with emphasis on the quint, and to a lesser degree the West anchor.
- LydAeolian or HeptaNa is the first destination point of the full Na tonalities progression through the whole or part of the sequence of natural harmonics. In the full Na progression or modulation path, secondary harmonics build up from TetraNa towards HeptaNa / LydAeolian. Then the secondary harmonics gradually modulate to tertiaries (or reciprocals) towards NaBal / PhrygIonian and may then resolve to PentaBal / PentaMinLa. Below are detailed graphical modulation path depictions of these and more such progressions.
