    The clef indicates which lines of the staff correspond to which
 pitches.  The three clef symbols in common use are:
 
      [image src="" alt="[image of music]" text="image of music"]
 
    Imagine a large staff of 11 lines centered on middle C, sometimes
 called a ‘grand staff’, with the bottom line representing low G and the
 top line high F:
 
      [image src="" alt="[image of music]" text="image of music"]
 
    Staves of five lines are usually used, and the clef superimposed on
 them indicates which five lines have been selected from this grand
 staff.  For example, the treble or G clef indicates that the top five
 lines have been selected:
 
      [image src="" alt="[image of music]" text="image of music"]
 
    The ‘curl’ of the G clef is centered on the line that represents the
 pitch G.
 
    In the same way, the bass or F clef indicates that the bottom five
 lines have been selected from the grand staff, and the alto or C clef
 indicates the middle five lines have been selected.  This relationship
 is shown below, where the notes show an arpeggio on a C major chord.
