Idiomelon
Idiomelon —pl. idiomela—is a type of sticheron found in the liturgical books used in the Eastern Orthodox Church, the Eastern Catholic Churches which follow the Byzantine Rite, and many other Orthodox communities like Old Believers. Idiomela are unique compositions, while avtomela or aftomela—sing. automelon, avtomelon or aftomelon —were used to create other hymns by a composition over the avtomelon's melody and following the poetic meter provided by the musical rhythm. The genre composed over these avtomela was characterised as prosomoion or prosomeion.
