Clefs
Clefs define the pitch range, or tessitura, of the staff on which it is placed. A clef is usually the leftmost symbol on a staff. Additional clefs may appear in the middle of a staff to indicate a change in register for instruments with a wide range. In early music, clefs could be placed on any of several lines on a staff.
G Clef (Treble)
The centre of the spiral defines the line or space on which it rests as the pitch G above middle C, or approximately 392 Hz. Positioned here, it assigns G above middle C to the second line from the bottom of the staff, and is referred to as the "treble clef." This is the most commonly encountered clef in modern notation, and is used for most modern vocal music. Middle C is the first ledger line below the staff here. The shape of the clef comes from a stylised upper-case-G.

F Clef (Bass)
The line or space between the dots in this clef denotes F below middle C, or approximately 175 Hz. Positioned here, it makes the second line from the top of the staff F below middle C, and is called a "bass clef." This clef appears nearly as often as the treble clef, especially in choral music, where it represents the bass and baritone voices. Middle C is the first ledger line above the staff here.
