Enharmonic: Difference between revisions

'''In regards to intervals or notes:'''

* Two intervals or notes an [[enharmonic diesis]] apart, such as the augmented fourth and the diminished fifth, or C♯ and D♭. In [[12edo]], such intervals or notes are tuned to the same size or pitch, so they are '''enharmonically equivalent'''. In any tuning whose [[perfect fifth]] is not the same as 12edo's, enharmonic intervals or notes are distinct.

* By extension, intervals mapped to the same number of steps in any [[temperament|tempered]] [[tuning system]]. This is technically a misnomer that arose from the ubiquity of 12edo. The clearer term is ''equivalent'' or ''equated''. For example, in [[5edo]], E and F are equivalent/equated since they are both mapped to 480 cents above C.

'''In regards to scales:'''

* A [[mos scale]] of 17 or 19 notes that is 7a 12b or 5a 12b with unspecified sizes for a and b (descended from 5L 2s such that diatonic enharmonic equivalents become distinct generic interval classes), which can be:

** [[12L 7s|12L 7s (m-enharmonic)]]

** [[12L 5s|12L 5s (p-enharmonic)]]

** [[5L 12s|5L 12s (s-enharmonic)]]

* The enharmonic genus, a {{w|genus (music)|genus}} in ancient Greek music theory containing scales with comma-sized steps
