22edo has two pairs of thirds: | 22edo has two pairs of thirds: one pair characteristic of the Superpyth diatonic scale, and one characteristic of Zarlino diatonic; despite most often being viewed as an 11-limit system, it lacks clear representation for the neutral thirds that are characteristic of 11-limit harmony. | ||
The | The superpyth minor third at 5\22 represents 7/6 with moderate accuracy, though it is often noted to be significantly less concordant than the JI representation. Its fifth complement is the superpyth major third at 8\22, which is an excellent representation of 9/7. This interval is perhaps better paired with 14\22 than with 13\22, as the former can be interpreted as 11/7 and thus provides the more consonant otonal 7:9:11 triad. | ||
The minor third at 6\22 is contentious in its interpretation; it is quite sharp for a minor third, though not nearly sharp enough to constitute a neutral third; by patent val, it represents 6/5 and 11/9, though in practice it does not accurately represent either of the two. Its fifth complement, the major third at 7\22, is a much clearer 5/4, having a relative error of less than 10%. | The zarlino minor third at 6\22 is contentious in its interpretation; it is quite sharp for a minor third, though not nearly sharp enough to constitute a neutral third; by patent val, it represents 6/5 and 11/9, though in practice it does not accurately represent either of the two.

The C Ionian scale in Superpyth is a perfect showcase of how common-practice harmony differs from that of 22edo; specifically, quartal harmony tends to provide a more resolved sound than tertian harmony does, due to the sharp fifth exaggerating the size of the chroma. Thus, our progression can resolve quite nicely to the tonic chord, Csus4 or G<sup>4</sup>/C. | The C Ionian scale in Superpyth is a perfect showcase of how common-practice harmony differs from that of 22edo; specifically, quartal harmony tends to provide a more resolved sound than tertian harmony does, due to the sharp fifth exaggerating the size of the chroma.

This allows us to restrict our progression to three-part harmony rather than switching between three- and four-part harmony, or doubling voices as is often done in common-practice progressions. | ||
Note also that a | Note also that a diatonic semitone occurs between the notes E and F; this allows us to achieve a false resolution onto the Fsus4 chord, or C<sup>4</sup>/F, in our progression by way of voice leading from a chord on E. For this example, I have chosen to use the Orwell Diminished triad over E, which provides a tense sound without sounding nasty. The Fsus4 and E<sup>ow</sup> chords also introduce B♭, which contrasts with the B♮ found in the Gsaj chord, displaying how notes pulled from outside of the base scale can be quite useful in writing harmonies. | ||

Thus, our four-chord progression is Csus4 - E<sup>ow</sup> - Fsus4 - Gsaj. This series of chords uses a combination of voice leading, tension-and-release paradigms, and circle of fifths movement to provide a dynamic and functional harmonic progression. | Thus, our four-chord progression is Csus4 - E<sup>ow</sup> - Fsus4 - Gsaj.
