Ekmelily is an extension for LilyPond that supports variable accidentals and key signatures for the notation of microtonal music in several equal-temperament tunings – 12, 19, 24, 31, 36, 48, 53, 72, 96-EDO – and in 5-limit JI. For this purpose, it introduces predefined and user-defined notation styles. Each style describes a set of symbols for the alterations, usually up to the five-quarters-tone. Furthermore, Ekmelily defines own note names based on the names for semi- and quarter-tones given in LilyPond.

Ekmelily requires LilyPond version 2.19.22 or higher.

See Esmuflily for other music symbols (clefs, note heads, articulations, etc.) from SMuFL compliant fonts.
