TetraNa progression

TetraNa progression — root and its three inversions

TetraNa inversions are not necessarily tonalities as such but underlying roots of tonalities. Thus they facilitate progressions and modulations. You can find further information on them including more Tetratonalities and their relatives on the page Tetratonalities, relations, and the miracle of nature.

TetraNa, as tetratonality, spans only four notes, the fundamental and initial three overtones of the harmonic series. Its progression rounds off the Tonalibus catalogue of tonalities, after it grew to a considerable number of entries. This unifies the overtone foundation with pattern progression, full and partial, progressive and regressive, as well as anchored and to some extent also not anchored.

Harmony is when opposites meet in unity and circles close — while always remaining open-ended. Tetratonality relations and progressions, including the miracle of nature, exemplify this quite visibly in their relative simplicity. Harmony in its widest sense includes and remains open to everything and all. Therefore, the Tonalibus catalogue is to remain open-ended though reaching for an elusive level of completeness of something that in its entirety will always escape complete human grasp, will always be greater and go further — harmony, here in its expression as myriad of anchored tonalities.
