U+1D1BD "𝆹𝅥𝅮" Musical Symbol Semiminima White Unicode Character

U+1D1BD "𝆹𝅥𝅮" Musical Symbol Semiminima White is a historical notation glyph representing a white (open) form of the semiminima, which corresponds to a quarter note in modern musical notation. This symbol originates from the era of white mensural notation used in Renaissance and early Baroque music, where note heads were left unfilled to indicate specific rhythmic values and temporal relationships. Unlike the modern black quarter note, the white semiminima is part of a system that differentiated note durations through the shape and filling of the note head, often appearing in manuscripts and scholarly editions of early music. Its inclusion in Unicode allows for accurate digital representation and text-based encoding of these historically significant musical symbols.
