A key signature indicates the scale the composition is based on. It shows which notes are sharp or flat throughout the piece, thus determining the tonality. It does not indicate which instruments to play the piece on, what dynamic markings to use, or what tempo to play the piece at. These aspects are indicated by other musical notation symbols and markings.
