Reed shutoff produces sharp acoustic pressure variations that drive the resonator

Evidence

A reed vibrating against a shallot shuts off the flow of air rapidly and totally, and the consequent acoustic pressure variations are the sound source provided to the resonator. — David Howard, Jamie Angus, coustics and Psychoacoustics, 1230
