Shifting resonance ratios as holes open would wreck woodwind tuning

Evidence

Clearly it is essential that the modes of the resonator retain their frequency ratios relative to each other as the tone holes are opened, or else the instrument’s tuning will be adversely affected as higher modes are reached. — David Howard, Jamie Angus, coustics and Psychoacoustics, 1239
