Before You Play

 Assembling the Sousaphone

Connect the bell to the body so that the bell is fac-

ing the same direction as the player's face.

Completed assembly

Loosen the bell screws. Firmly holding on to

the bell on both sides, rotate the bell slowly

while inserting the bell into the bell joint on

the main body. After the bell is positioned,

tighten the three bell screws so that each screw

applies the same amount of pressure against

the bell.

* During rests, make sure that the bell screws are

tightened fi rmly.

Never loosen the screws on the copper brac-

ing holding the main coils together. Doing

so may cause the coils to separate resulting

in injury. Also, regularly check that the at-

tachment screws on the main tubing are

tightened fi rmly.
