Answer 2

In music theory and notation, a key signature is a set of sharp or flat symbols placed on the staff at the beginning of a musical composition or section to indicate the key of the music. A key signature tells the musician which notes in the composition are to be played sharp or flat, and it helps to establish the tonality of the piece. A key signature can also help musicians to identify the key of a piece when reading sheet music and to play the correct notes without having to constantly refer to accidentals (sharps, flats, or naturals) throughout the composition.
