This symbol is part of a larger set of characters that encode the vocal and instrumental signs found in surviving Greek musical texts, primarily from the Hellenistic and Roman periods. Unlike the alphabetic notation system for vocals, instrumental notation used a distinct set of symbols, often derived from curved forms, to indicate pitch and performance technique for instruments like the aulos.
