Accidentals: Sharps, Flats & Naturals
Accidentals are the "spices" of music. They alter the pitch of a note, raising or lowering it to create new sounds.
An accidental is a symbol placed to the immediate left of a notehead. It tells you to play the note slightly higher or lower than its "natural" white-key version.
💡 Think of them as half-steps: the smallest distance between two keys on a piano.
