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

• Tritone or blues tonality matrix: The octave includes the tritone plus for a heptatonality one, for a hexatonality two, and for a pentatonality three Reach steps (augmented seconds). These take off from the fundamental or from the quint. They are not framed by half steps (or semitones), of which there are three for hepta-, two for hexa-, and one for pentatonalities. When more than one of them, then some are consecutive.
• Hexatonality matrix: The octave generally includes one Reach step, four whole steps, and a single half step (or semitone). Two or three (or exceptionally all four) whole steps appear consecutively. Thus there are two pairs of consecutive whole steps or a trio plus a single. They are framed by the half step on one side and the Reach step on the other. Exceptionally there can be two Reach, two whole, and two half steps. Plus there is one case with three Reach and three half steps.
• HexaBlue: The name indicates that this a hexatonic version of a tritone or blues tonality.
• Step pattern: Ascending from the fundamental (tonic or Do), a Reach step leads to a whole step followed by a pair of consecutive half steps. Then comes another Reach step. Finally a whole step leads up to the octave.
• Scale intervals: Minor third, quart, tritone, quint, and minor seventh.
• Tetrachords: The lower and upper tetrachord are both Blue.
• Harmonic axes: There is one axis, which is vertical, N-S.
• Primary harmonic anchors: The fundamental or North anchor is fully present. The East anchor is partial, with its head and right leg only, and the contrasting or South anchor with only its head. The West anchor is completely absent.
• Secondary harmonic anchors: Two secondary anchors are present, SE and WN. Both emphasize the fundamental North anchor, the quart, and the East anchor.
• Two blue Reach steps: The presence of two blue Reach steps, one in both the lower and the upper tetrachord, results in a most pronounced blues flavor.
• Hexa- to heptatonality correlation: HexaBlue is equivalent to PhrygBlue without its minor second, to MinBlue without its major second, or to BlueMix without its major sixth.
