# Subminor interval

Subminor minor third on G  .
Origin of large and small seconds and thirds in harmonic series.[1]

In music, a subminor interval is an interval that is noticeably wider than a diminished interval but noticeably narrower than a minor interval. It is found in between a minor and diminished interval, thus making it below, or subminor to, the minor interval.

## Second

Thus, a subminor second is intermediate between a minor second and a diminished second (enharmonic to unison). An example of such an interval is the ratio 26:25, or 67.90 cents. Another example is the ratio 28:27, or 62.96 cents.

## Third

A subminor third is in between a minor third and a diminished third. An example of such an interval is the ratio 7:6  , or 266.87 cents,[2][3] the septimal minor third, the inverse of the supermajor sixth. Another example is the ratio 13:11, or 289.21 cents.

## Seventh

A subminor seventh is an interval between a minor seventh and a diminished seventh. An example of such an interval is the 7:4 ratio, the harmonic seventh.

## Use

Composer Lou Harrison was fascinated with the 7:6 subminor third and 8:7 supermajor second, using them in pieces such as Concerto for Piano with Javanese Gamelan, Cinna for tack-piano, and Strict Songs (for voices and orchestra).[4] Together the two produce the 4:3 perfect fourth (a supermajor second above a subminor third is the perfect fourth).[5]
