U+1D0D0 "𝃐" Byzantine Musical Symbol Diesis Apli Dyo Dodekata is a specialized notation from the Byzantine musical tradition, part of the extensive suite of symbols used to notate the complex microtonal intervals and vocal ornamentation of Eastern Orthodox chant. This particular symbol represents a specific type of diesis, or microtonal accidental, indicating a pitch alteration of two "dodekata," which are units of the Byzantine tuning system equivalent to a small, precise interval. As a member of the Byzantine Musical Symbols block, it is employed in liturgical manuscripts to guide singers in achieving the correct pitch inflection and melodic nuance required for the performance of ancient hymns and religious music.
