Following table for acoustical lengths, corrected for temperature and gas composition in a wind instrument, is adapted from Cees Nederveen's thesis. Wavelengths (in millimetres) are calculated for a sound velocity of 346 m/s (sonud velocity in the damp and warm air inside the tube is higher than ouside). The table gives notes as they sound, not as they're written. It is based on a concert pitch of A=440Hz and on equal temperament.
