n a clarinet, air is vibrated by a reed in the instrument’s mouthpiece. The pitch of a particular note on a clarinet is determined by the length of the vibrating column of air between _____.

the mouthpiece and the musician’s fingers
the musician’s fingers and the bell at the end of the instrument
two of the musician’s fingers
the mouthpiece and the bell at the end of the instrument

The correct answer is: the mouthpiece and the bell at the end of the instrument. The length of the vibrating column of air between the mouthpiece and the bell can be altered by the musician using their fingers to open or close the tone holes. This changes the pitch that is produced.
