Temperament naming: Difference between revisions

Line 6:

Below are explained some notable features of naming which might otherwise be confusing to beginners of RTT.

~~==== Comma name and temperament name ====~~

With a few exceptions, a name of a comma implies an eponymous temperament that tempers out the comma alone and vice versa, in which case we consider it an official common name. A description, or descriptive name, is an alternative, typically longer, term that conveys some additional information at the cost of lacking in uniqueness. For example, 225/224 is named the ''marvel comma'', and tempering it out results in the marvel temperament. Meanwhile, it has a descriptive name ''septimal kleisma'' that perhaps dates back to earlier times.

==== Use of a name for a temperament and its extensions ====

Line 15:

Line 12:

* If a temperament does not have an obvious extension, or has multiple competing extensions, none of them is canonical;

* [[Weak extension]]s are never canonical since their structures are very different.

==== Use of a related pair of names for a comma and its associated temperament ====
