Tonality of the moment: HexaBluNaReach

The tonality of the moment for autumn 2025 is HexaBluNaReach.

HexaBluNaReach is a BluNa and Reach hexatonality.

Hexatonalities consist of six pitches to the octave. HexaBluNaReach contains no whole steps but three Reach steps (augmented seconds) and three halftone steps alternating with each other. BluNa indicates that it is a partial blue tonality (Blu) with an initial Reach step off the fundamental to the minor third, with the quint but no tritone. With the quint and the major third it includes the initial or most prevalent natural overtones (Na). BluNa thus indicates that both the major and minor third are present and generally no quart. Therefore the second Reach step leads from the major third to the quint over the middle of the scale, a quality shared with the Mid tonalities, which however don’t have the initial Reach step. Finally, the upper tetrachord of HexaBluNaReach features, as the name indicates, a regular Reach step, that is from the minor sixth to the major seventh.

All this gives this special tonality a unique symmetry overall and a remarkable equilibrium between major and minor. Its name could therefore also be minor major or major minor.

You may enjoy a sound sample or tonality loop as sound mantra for contemplation or meditation. This can help with upliftment, purification, and focusing. Or it could simply be used as soothing background sound for relaxation and regeneration. If you care to hum, chant, or sing along, you could use a spiritually charged syllable like Ōṃ / Aum ॐ, or HU, or another mantra syllable that suits you.
