Piano/Key Signature
< Piano
The key signature of a piece of music is the sharps or flats listed after the clef. This is to avoid the repetiton of accidentals in the score. They are listed on every line of music, which signifies what key the composer has chosen.
There is a key signature for each major key (C Major has no sharps or flats). Each major key, in turn, shares its signature with the minor key whose scale begins three semitones lower - in other words, on the 6th note (the submediant) of the major scale.
