A trombone is a musical instrument that is made of brass and has a long tube with a curved end. It is played by blowing air into it and using a slide to change the length of the tube, which creates different pitches. Trombones are often used in orchestras, jazz bands, and other types of music groups. If you hear someone talking about a trombone, they are probably referring to this musical instrument.
