U+1D12A "𝄪" Musical Symbol Double Sharp is a notation glyph used in musical scores to indicate that a note should be raised in pitch by two semitones, or a whole step, from its natural state. This symbol, visually resembling an elongated 'X' or a stylized cross, is defined within the Unicode Musical Symbols block and is designed for use in digital music notation systems, providing a precise and universally recognized character for composers and arrangers.
