Jazz trombone

The trombone is a musical instrument from the brass instrument family. Trombone's first premiere in jazz was with Dixieland jazz as a supporting role within the Dixie Group. This role later grew into the spotlight as players such as J.J. Johnson and Jack Teagarden began to experiment more with the instrument, finding that it can fill in roles along with the saxophone and trumpet in bebop. The trombone has since grown to be featured in standard big band group setups with 3 to 5 trombones depending on the arrangement.
