Valide trombone

Hybrid brass instrument with both a trombone-like slide and valves

The valide trombone is a hybrid valve trombone invented in the 1940s by jazz musician Brad Gowans. It features both a set of three piston valves and a slide to vary the pitch. The slide on the valide is positioned within the valve section and is shorter than a regular trombone slide, only covering four slide positions instead of the usual seven. The slide does not lock, requiring the player to hold the slide at all times, and encouraging the player to use both the valves and the slide together.
