Calculations on location and dimensions of holes in a clarinet
Centraal laboratorium TNO
For a cylindrical woodwind and in particular for a clarinet, methods are derived to calculate location and diameier of the holes. In a simple way the calculations are carried out for each hole separately, and independently of the other holes. Corrections are introduced for the influence on the resonance frequency of the overblowing hole and of the row of closed holes in the main tube. The usefulness of the formulae is proved by calculating all holes of a B-flat-Boehm-clarinet. It appears that if the clarinet is assumed to be cylindrical from the top downwards, the pressure antinode is located at 7 mm below the top. Some phenomena accompanying tuning of the clarinet are clarified.
