The trigger mechanism
The main difference between the bass trombone and the trigger trombone is the trigger mechanism.

This makes it possible for the trigger trombone to play notes that are not normally possible on a bass trombone.
The trigger mechanism can also be used to create special effects, such as glissandi and portamenti. This makes the trigger trombone a versatile and expressive instrument that is well-suited for a variety of musical genres.
