Put your head and right arm through the sousaphone's center opening.
Rest the sousaphone on your left shoulder for support and place your left hand on the bottom of the instrument for additional support.
Adjust the sousaphone's position on your shoulder until the bell is directly above your head, facing forward, and the tubing leading to the bell is behind your neck.
Place the index, middle and ring fingers of your right hand on the three valves.
Bring your lips to the mouthpiece to begin playing the instrument.
