U+1D1BA "𝆺" Musical Symbol Semibrevis Black Unicode Character

U+1D1BA "𝆺" Musical Symbol Semibrevis Black is a notation symbol from the Musical Symbols block, specifically designed for representing a black, filled-in whole note in historical or mensural music notation. Unlike the modern hollow semibreve, this character's solid form indicates a specific rhythmic value or style within early Western music manuscripts, where it often denotes a breve or a shortened duration depending on the mensural context. Its inclusion in Unicode allows digital typesetting of medieval and Renaissance scores, preserving the distinct visual appearance of this note shape for scholarly and performance purposes.
