TOPIC: KEY SIGNATURE

DEFINITION OF KEY SIGNATURE

Key signature refers to a set of marks in form of musical signs like sharp and flat, introduced just before the treble and bass clef or at the beginning of a musical staff of a printed manuscript to indicate the key a musical piece is. Key signature is a group of sharps or flats placed to the right of the clef on a staffto identify the key in a musical piece.

USES OF KEY SIGNATURE

1. A key signature designates notes that are to be played higher or lower than the corresponding natural notes and applies to the end of the piece or up to the next key signature.
2. A key signature serves as a guide to the performer of a piece of music.
3. The key signature determines the pattern of accidentals, that is the sharps and flats to be played, and reappears at the beginning of each staff.
