Clefs

Clefs are a symbol used to indicate the pitch of written notes. It is placed on a stave and indicates the name and pitch of the notes on one of the lines. This line serves as a reference point by which the names of the notes can be named.

There are three major types of clefs: The Treble clef is the most commonly used clef for upper clarinets like the Bb Clarinet or the A Clarinet while the bass clef is used by Bass Clarinets. The Alto Clef is rarely used as even the alto clarinet uses the treble clef. However, the Alta Octave Treble Clef is used sometimes when the music is filled with upper altissimo register notes. The clef means "an octave above the treble clef"
