The flat sign (♭) is a standard musical symbol indicating that a note should be lowered in pitch by one semitone. Found in the Unicode Miscellaneous Symbols block, it sits alongside the sharp (♯) and natural (♮) signs. While essential for digital sheet music and music theory, it frequently pops up on social media when people discuss tuning instruments, singing off-key, or sharing chord progressions.
