caption: The image shows a brass trombone on a white background. The instrument has a long, cylindrical body with a bell-shaped end and a wide, flared bell at the end. The bell is made of brass and has a bright, shiny finish. The trombones are positioned in a symmetrical pattern, with the bell facing up and the other end facing down. The white background provides a stark contrast to the golden color of the instrument, making it stand out.
