Superfourth: Difference between revisions

Line 1:

A '''superfourth''' is an [[interval]] too wide to sound like a [[perfect fourth]] and too narrow to sound like a [[tritone]]. [[Margo Schulter]], in her article [http://www.bestii.com/%7Emschulter/IntervalSpectrumRegions.txt Regions of the Interval Spectrum], proposes an approximate range for a superfourth to be from 528¢ to 560¢. Some of the simplest superfourths in [[Just intonation]] are [[11/8]] (about 551.3¢) and [[15/11]] (about 537¢), both undecimal (11-based) superfourths; and [[48/35]] (about 546.8¢) and [[49/36]] (about 533.7¢), both septimal (7-based) superfourths.

The inversion of a superfourth is a [[subfifth]].

The inversion of a superfourth is a [[subfifth]]. Notably, superfourths tend to be more consonant than subfifths.

Of course, this categorization should not be taken for granted. Since music is subjective and culturally influenced, the borders of what is a superfourth are "fuzzy". Other description are possible and legitimate.
