The tonality of the moment for winter 2025-2026 is PentaCor.
PentaCor is a Core tonality and a partially anchored basic pentatonality. It is the tonality of “Flashes of radiant cognizance” from September 2025, which becomes a new Tonalibus single release on December 22. PentaCor is also the foundation of “Let’s listen” / “Let’s talk” from June 2022, which modulates from PentaCor via HexaCorMix (with the major sixth) to LoReachUpMix (with the minor second). An alternate smooth modulation path is to ReachUpMix (with the major second) instead, as used in “Journey Around the Sun” from April 2021 (PentaCor via ReachUpMix to Dorian and back).
Core tonalities are a diverse collection of specific hepta-, hexa-, and pentatonalites with a common core. Though only partially or progressively anchored (with the exception of fully anchored BlueMix), they are most uniquely anchored in that they contain all four corners of the sound temple. Besides the fundamental or octave, these are the minor third, tritone, and major sixth. As a result of containing all four corners of the sound temple, they tend towards dissolving tonality. Thus they can open up more freedom in experiencing sound.
The addition of the quint to the four corners of the sound temple produces the pentatonality PentaCor. The quint strengthens its fundamental and anchors it in a more common sense of harmony and tonality.
