Abstract
Three valve assemblies are linked with finger buttons and inserted into a pipe structure of a trumpet for changing the length of air column, and a supporting system assists a player in fingering on the finger buttons; sensors are adhered to the finger buttons so as to supply a detecting signal representative of force exerted on the finger buttons by the player to a controlling unit; when the force exceeds over a threshold, the controlling unit energizes actuators connected to the valve assemblies so as to make the player feel the valve assemblies lightly changed.
