The '''diesis''' is a small melodic unit of about an [[augmented comma]]'s size. The specific range varies considerably among musicians. | |||
== Just intervals == | |||
Some just intervals have been named according to this definiton of diesis. | |||
* [[Porcupine comma]], or ''maximal diesis'' (49.2 ¢) | |||
* [[Magic comma]], or ''small diesis'' (29.6 ¢) | |||
* [[Tetracot comma]], or ''minimal diesis'' (27.7 ¢) | |||
* [[49/48]], the ''large septimal diesis'' (35.7 ¢) | |||
* [[50/49]], the ''small septimal diesis'' or ''septimal tritonic diesis'' (35.0 ¢) | |||
This is not to be confused with the [[diesis (scale theory)|related sense of the same term]], for which the [[648/625|major diesis (648/625)]] was named while being way wider than the "maximal diesis". | |||
== History == | |||
The earliest usage of the term ''diesis'' was due to {{w|Philolaus}} in [[ancient Greek music]] to refer to an interval that is known as the [[256/243|limma]] today. Another usage, also in ancient Greek theory and notably used by {{w|Aristoxenus}}, would refer to a number of quartertone-sized intervals. In more recent times, {{w|Marchetto da Padova}} used it for fifth-tones, and finally, the modern diesis centered around [[31edo|1\31]] is due to [[Adriaan Fokker]]. | |||
