The tonality of this month of September is TetraNa, a Na(tural harmonics) tonality and exceptional tetratonality. Because it is the only tetratonality currently in the Tonalibus catalogue, it is listed along with pentatonalities. It is the first, most fundamentally pure Na tonality because it contains only the first four natural overtones. Na tonalities are uniquely harmonious and ideally span over multiple octaves, preferably three or four. They follow the sequence of natural harmonics or overtones and eventually form an arch with secondary harmonics turning into tertiary ones (or reciprocals) and thus lead to more commonly known tonalities. TetraNa is the entry point to this progression. Na(tural harmonics) tonalities will soon appear in the Tonalibus catalogue.

You may enjoy a sound sample loop, such as the one of the tonality of the month, as sound mantra for contemplation or meditation, for upliftment, focusing, or simply for relaxation and regeneration as soothing background sound. Further, you could hum or chant along, for example using HU or another mantra syllable, and tune yourself to the fundamental.
