U+1D157 "𝅗" Musical Symbol Void Notehead Unicode Character

U+1D157 "𝅗" Musical Symbol Void Notehead is a specialized glyph from the Musical Symbols block used in Western musical notation to represent a notehead that is not filled in, meaning it is hollow or void. This shape is typically associated with longer note durations, such as whole notes or half notes, where the absence of solid fill visually indicates a sustained or less percussive attack. In musical scores, the void notehead serves a distinct function compared to its filled counterpart, allowing composers and engravers to specify rhythmic values and articulation without relying solely on stem and flag conventions.
