The trombone is a musical instrument in the brass family. Like all brass instruments, it is a lip reed aero phone and sound is produced when the player’s buzzing lips cause the air column inside the instrument to vibrate. The trombone is usually characterized by a telescopic slide with which the player varies the length of the tube to change pitches, although the less common valve trombone uses three valves similar to those on a trumpet.

Therefore, the most frequently encountered trombones, the tenor and bass, are the tenor and bass counterparts of the trumpet. Select this link to view our Gold and Red Ornaments. The trombone consists of a cylindrical tube bent into an elongated "S" shape in a complex series of tapers, the smallest being at the mouthpiece receiver and the largest being at the throat of the bell, before the flare for the bell begins. Careful design of these tapers is crucial to the intonation of the instrument. Select this link to view our People and Profession Ornaments. The telescopic 'slide' allows the player to extend the length of the air column, lowering the pitch. In order to prevent friction from slowing the action of the slide, additional sleeves were developed during the Renaissance and these stockings were soldered onto the ends of the inner slide tubes. Nowadays, the stockings are incorporated into the manufacturing process of the inner slide tubes and represent a fractional widening of the tube to accommodate the necessary method of alleviating friction. This part of the slide must be lubricated on a frequent basis. Additional tubing connects the slide to the bell of the instrument through a neck pipe and back bow or U bend. The joint connecting the slide and bell sections is furnished with a ferrule to secure the connection of the two parts of the instrument, though older models from the early 20th century and before were usually equipped with friction joints and no ancillary mechanism to tighten the joint.
