The trombone is a brass instrument that changes pitch by lengthening or shortening the tube with a sliding section. The player’s buzzing lips set the air column in vibration, and the slide selects the harmonic series for each position.

Its sound is powerful, flexible, and capable of both majestic statements and agile passages. In the orchestra the trombones often provide a solid brass foundation and dramatic climaxes. Jazz trombonists have developed a highly expressive style that includes slides, growls, and lyrical solos. The instrument also appears in bands and brass ensembles.

Learning the slide positions and developing a reliable embouchure take time. The trombone’s ability to move continuously between pitches allows for expressive glissandos that other brass instruments cannot easily match. Different sizes, including the bass trombone, extend the family’s range.

A well-played trombone can be both noble and surprisingly agile.
