Abstract : Two movements seem possible for the lips of the trumpet player, upward and outward striking .A basic model, using one or the other movement, is proposed so that its behavior can more easilybe understood and controlled. The two movements are compared. The model appears as adynamic system of two loops coupled by a nonlinear function, one loop describes the dynamicsof the single mass and the other represents the acoustic wave in the bore. Being much simpler,this model is simulated in real time on a workstation, allowing for easy experimentation ofdifferent designs and parameter values.
