Interseptimal interval: Difference between revisions

Line 44:

While this does not give the interseptimals a single distinct ''notational'' name, it does reflect their ambiguity and flexibility with regards to the surrounding interval categories that many are so fond of. Furthermore, as both identities are exactly 12 notational fifths apart (i.e a direct analogue of the [[Pythagorean comma]]), composers can use a mechanism similar to the [[Color notation|"po and qu" of Color Notation]], or the plus and minus accidentals (+/−) proposed in [[Rational Comma Notation (RCN)|Rational Comma Notation]], to freely switch between the two identities.

Alternatively, one can use the ''ultra-'' prefix for sharpening by ~50¢ and ''infra-'' for flattening by ~50{{c}}, analogous to ''super-'' and ''sub-'' for modifications by ~~[[64/63]] (in a [[12edo]]-related context such as [[36edo]], 33~~{{c}}).

Alternatively, one can use the ''ultra-'' prefix for sharpening by ~50¢ and ''infra-'' for flattening by ~50{{c}}, analogous to ''super-'' and ''sub-'' for modifications by ~30{{c}}.

* semifourth/chthonic = ultramajor second, inframinor third

* semisixth/naiadic = ultramajor third, infrafourth
