U+1D0BA "𝂺" Byzantine Musical Symbol Fthora Diatoniki Pa Unicode Character

U+1D0BA "𝂺" Byzantine Musical Symbol Fthora Diatoniki Pa is a specialized glyph used in the Byzantine musical notation system to represent a specific chromatic alteration or inflection for the note Pa, indicating a diatonic tuning that modifies the pitch within a musical phrase. Originating from the rich tradition of Eastern Orthodox liturgical chant, this symbol belongs to a larger class of accidentals called fthorai, which guide singers in adjusting intervals to maintain the correct modal character of a composition. The character is encoded in the Unicode Byzantine Musical Symbols block, which was added to the standard to support the digital representation and preservation of this ancient notational heritage.
