9. o What is a key signature?
o Why are key signatures important?
o How is a key signature identified and written?
A key signature is any of several combinations of sharps or
flats
that appear after a clef at the beginning of a line of music
Key signatures determine which accidentals occur
throughout a piece of music without having to be placed in
front of individual notes (less ink on the page!)
Key signatures are identified by a collection of sharps or flats that appear
after a clef. They are written using an order of sharps and flats.
