A key signature indicates what scale the composition is based on. It shows which notes are to be played as sharps or flats throughout the piece unless otherwise indicated by accidentals (sharp, flat, or natural symbols that appear within the music to alter the pitch of a single note). The key signature is placed at the beginning of a piece of music, right after the clef and before the time signature.
