Woodwind tone holes must preserve mode frequency ratios to stay in tune
Evidence
Preserving a constant frequency ratio between the vibrational modes as the holes are opened is essential in all woodwinds and provides a limitation on the types of air column (often referred to as the bore) that are musically useful. — David Howard, Jamie Angus, coustics and Psychoacoustics, 1240
