Reed instruments can use resonators shorter than full pipe length

Evidence

Because the reed itself fixes the f0 of the pipe, the resonator does not need to reinforce the fundamental, and fractional length resonators are sometimes used to support only the higher harmonics. — David M. Howard, Jamie Angus, Acoustics and Psychoacoustics, 1208
