Interval quality: Difference between revisions

Line 12:

In [[moment of symmetry]] (MOS) scales, each interval class contains two intervals except for the unison class, which only contains the unison class. The two interval classes that correspond to the [[Modal UDP notation#Generalizing to arbitrary MOS scales: bright and dark generators (chroma-positive and chroma-negative)||bright and dark generators]] contain only perfect intervals except for one, which corresponds to the "wolf" interval, which is qualified as either ''augmented'' or ''diminished'' depending on its size relative to the perfect generator, or sometimes ''imperfect''. The other interval classes contain major and minor intervals.

Scales with higher [[interval variety]] ~~require additional~~ qualities. Although there are no standard labels yet, ''large'', ''medium'' and ''small'' can be used for variety-3 interval classes.

Scales with higher [[interval variety]] have interval classes with more qualities. Although there are no standard labels yet, ''large'', ''medium'' and ''small'' can be used for variety-3 interval classes.

The [[harmonic series]] taken a scale theoretically contains infinitely many interval qualities for each interval class. For that reason, relative quality is rarely used in that context and other tools are used to describe the variety of intervals found in [[just intonation]] taken as a whole, such as absolute interval quality.
