abstract:
The technique used by harmonica players to alter the pitch of note being played, by vocal tract manipulations, is described. Observations of the effect from the player's point of view, and results of experiments using a mechanically blown instrument are presented. An acoustical analysis of the effect using the small signal approximation, and including both reeds in each airway in the modell, yields predictions in accord with observations. (17 refs.)
