Use your other hand to hold on to the bell section. * After assembly is complete, make sure that the slide brace is used to hold the instrument.

If you hold on to the tuning slide, the tuning slide may come off or poor stability may result in the instrument being bumped. 3. Attach the slide section to the main bell section. Attach the slide so that it is at a suitable angle when you play. * Never insert the mouthpiece with force or unnecessary strength. The mouthpiece may become stuck in the receiver. 22
