Instrument makers shape bore profiles to tune woodwind modes around tone holes
Evidence
By creating local constrictions or enlargements, the skilled maker is able to set up a woodwind instrument to compensate for the presence of tone holes such Displacement FIGURE 4. — David M. Howard, Jamie Angus, Acoustics and Psychoacoustics, 1225

Broader Connections
- Local bore changes tune instrument modes by their position relative to pressure nodes
#expands(0.92) - A local bore constriction can tune individual pipe modes separately
#expands(0.90) — David M. Howard, Jamie Angus, Acoustics and Psychoacoustics, 1225 - Fixed inter-modal frequency ratios constrain musically useful bore shapes
#qualifies(0.82) - Woodwind tone holes must preserve mode frequency ratios to stay in tune
#qualifies(0.78) - Tone-hole opening must preserve modal frequency ratios for correct tuning
#qualifies(0.78) — David M. Howard, Jamie Angus, Acoustics and Psychoacoustics, 1211 - Shifting resonance ratios as holes open would wreck woodwind tuning
#qualifies(0.75) — David Howard, Jamie Angus, coustics and Psychoacoustics, 1239 - Mouthpiece geometry permanently sculpts instrument tone via early echoes
