piston valve


A mechanism on a brass instrument that, when depressed, directs the air column along additional tubing inside the instrument. This additional tubing produces a different fundamental and harmonic series. The piston valve is comprised of a cylinder inside a brass housing that must be depressed completely to allow the tubing to align properly.
