Motion of the lips of brass players during extremely loud playing

Résumé

When a brass instrument is played loudly the energy level of the higher harmonics increases dramatically. The generally accepted explanation for this is non-linear steepening of the wavefront and generation of shock waves within the instrument bore. However, it has also been suggested that changes in the player's lip vibration could play a role in generating this `brassy' sound. To test this hypothesis, the dependence of lip opening-area on time has been measured for di®erent dynamic levels in trombones and horns. Results suggest that the ehaviour of the open area does not change dramatically when the instrument enters the brassy regime.
