U+1D093 "𝂓" Byzantine Musical Symbol Digorgon Parestigmenon Aristera Kato is a specialized notation used in Byzantine musical chant notation, representing a specific pitch inflection or ornamentation that combines a double gorgon (a quickening or rhythmic alteration) with a parestigmenon (a marking indicating a note is sung from a lower neighboring pitch), performed on the left side and moving downward, as the Greek words "aristera" and "kato" indicate. This character is part of the Byzantine Musical Symbols block in Unicode, and its precise shape and positioning in the musical text guide singers in the Eastern Orthodox tradition to execute a particular melodic nuance, preserving the intricate oral tradition of psaltic art.
