The “womp womp” trombone sound is a distinctive glissando effect created by rapidly moving the trombone slide up and down while playing a note. It is often used to create a humorous or ironic effect in music, particularly in jazz and popular music.
To perform the womp womp trombone, start by playing a note in the middle of the trombone’s range. Then, quickly move the slide up and down while continuing to play the note. The faster you move the slide, the more pronounced the womp womp effect will be. You can also vary the pitch of the note you are playing to create different effects.
