U+1D151 "𝅑" Musical Symbol Triangle Notehead Up Right Black Unicode Character

U+1D151 "𝅑" Musical Symbol Triangle Notehead Up Right Black is a specialized glyph within the Musical Symbols block, used in modern music notation to represent a notehead that is shaped like a filled triangle pointing upward and to the right. This symbol is part of a set of unconventional noteheads employed primarily in avant-garde or contemporary compositions, where it may indicate a specific timbre, articulation, or percussive effect rather than a standard pitch duration. Its inclusion in Unicode ensures that composers and music software can reliably encode and display this alternative notation across digital platforms.
