User:Xenllium/Xenllium's circulating scales

Below are listed circulating scales introduced by Xenllium.

Xentwelve

Xentwelve is a 12-tone circulating scale based on 12 equal temperament. In summary, it is close to 1/3-comma meantone in the natural keys and Pythagorean tuning in the remote keys. The generator is a perfect fifth, which comes in three sizes, with eight pure fifths (at C–G, C♯–G♯, E♭–B♭, E–B, F–C, F♯–C♯, B♭–F and B–F♯, frequency ratio 3/2), three 1/3-comma meantone fifths (at D–A, G–D and A–E), and one narrow schismic fifth (at G♯–D♯ (A♭–E♭), frequency ratio 16384/10935). It derives two major thirds exact 5/4 (at C–E and G–B) and one minor third exact 6/5 (at E–G), with a pure major chord (at C–E–G) and a pure minor chord (at E–G–B).
