U+1D159 "𝅙" Musical Symbol Null Notehead Unicode Character
Unicode Version 17.0
𝅙
U+1D159 "𝅙" Musical Symbol Null Notehead is a specialized glyph used in the domain of musical notation, specifically within the context of the Musical Symbols block. It represents a notehead that is intentionally rendered as invisible or absent, often employed for educational or analytical purposes to indicate a rhythmic space where a note could exist but is not sounded, or to mark a placeholder in music theory exercises and graphic scores. Unlike standard noteheads that denote a specific pitch and duration, this symbol carries no sonic value and functions purely as a conceptual marker for structural or pedagogical clarity.
