How to Put Together a Trombone
Trombones have three main components. ( Images)

Trombones contain three main components: the bell section, the slide, and the mouthpiece. The bell section contains the tuning slide, the bell and three braces. The slide contains two braces and a water key, or spit valve, for releasing accumulated saliva. The bell is typically held in the left hand, while the performer adjusts the slide bar with his right hand to alter the path of air between the mouthpiece and the bell, thereby altering the pitch of the instrument.

Skill level:


  1. 1

    Hold the slide vertically so the two ends of the slide are pointing upward.

  2. 2

    Locate the short end of the slide. Insert the mouthpiece into the short end, twisting gently with your right hand to create a snug fit.

  3. 3

    Insert the long end of the slide into the bell section's slide receiver.

  4. 4

    Twist the nut to secure the slide to the bell section.
