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 he/she has chosen.

There is a key signature for each major key (though C major, which has no flats or sharps, is a 'blank'). 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.
