Quick Summary
In music, a "sharp" is a symbol (\u266f) that indicates a note should be raised by a semitone. For example, F-sharp is a semitone higher than F. This is a fundamental concept in musical notation, where sharps are used in key signatures to establish the tonality of a piece. Accidentals, including sharps, can also be used within a measure to temporarily alter a note's pitch. Some notes, like E-sharp, sound the same as another note (F) in equal temperament tuning, a concept known as enharmonic equivalence.123456
