Completing the Cone
Fact or Fallacy
1) Get the horn in tune.
2) Measure how much of the neck is inserted into the mouthpiece.
3) Measure the volume of the neck.
4) Measure the volume of the mouthpiece.
6) Calculate the theoretical mouthpiece volume.
measured volume = 24ml
24.0 - 6.86 = 17.1
vs
a theoretical 14.9

Problems with the analysis
Reliance on individual player's skill in tuning (Maybe alto and tenor players always play sharp?)
Small sample size
Measurement resolution (scale only measured to the nearest gram)
Faulty geometric assumptions
