U+1D0B6 "𝂶" Byzantine Musical Symbol Enarxis Kai Fthora Vou Unicode Character

U+1D0B6 "𝂶" Byzantine Musical Symbol Enarxis Kai Fthora Vou is a notation mark used in Byzantine chant notation, representing a specific musical instruction that combines an enarxis, a sign indicating the beginning of a melodic pattern, with a phthora vou, a modulating symbol that alters the pitch or mode by a whole tone step downwards. This character belongs to the Byzantine Musical Symbols block in Unicode, which encodes the neumes and signs of the medieval and Eastern Christian liturgical music tradition. In practice, the symbol guides a singer or chanter to start a new musical phrase while simultaneously applying a vocal inflection or modal shift, thereby preserving the complex tonal system of Byzantine hymnody.
