Ekmelily is an extension for LilyPond
that supports variable accidentals and key signatures
for the notation of microtonal music in several tunings.
It currently supports the equal-temperament tunings
12, 19, 24, 31, 36, 48, 53, 72, and 96-EDO,
as well as 5-limit JI.
It introduces predefined and custom notation styles.
Each style describes a set of accidental symbols for the alterations,
up to the five-quarters-tone at most.
Furthermore, it defines own note names
based on the names for semi- and quarter-tones given in LilyPond.
Ekmelily requires LilyPond version 2.24 or higher.
See Esmuflily for the support of other SMuFL music symbols.
