When we talk about music theory, sharps and flats are common terms used to describe the alteration of a note's pitch. Sharps are used to raise a note's pitch by a semitone, while flats lower a note's pitch by a semitone. While these two terms are staples in the music world, there are also other synonyms that can be used interchangeably with sharps and flats. Accidentals, altered notes, and chromatic notes are some of the synonyms used to describe notes that have been raised or lowered in pitch. These terms may not be as commonly used as sharps and flats, but they are just as important in understanding music theory.
