	A bitetradic scale is a heptatonic (or in certain cases smaller) scale created by constructing two tetrads, one starting on 1/1 and one ending at the period. A special variety, the tertian bitetradic scale, is specifically created with two tertian seventh chords and a period of 2/1. Any heptatonic scale can be analyzed as bitetradic; for example, the 12edo Ionian scale consists of a Maj7 chord on the 1/1 and a Min7 chord ending at 2/1.

A bitetradic scale is a heptatonic (or in certain cases smaller) scale created by constructing two tetrads, one starting on 1/1 and one ending at the period. A special variety, the tertian bitetradic scale, is specifically created with two tertian seventh chords and a period of 2/1. Any heptatonic scale can be analyzed as bitetradic; for example, the 12edo Ionian scale consists of a Maj7 chord on the 1/1 and a Min7 chord ending at 2/1.
to do: document rashtic; talk about properties if applicable, and extensions to other odd numbers [possible to do even numbers by overlapping one interval?], try this out with other tertian structures than diatonic
