Abstract
A saxophone has a complicated key mechanism for selectively closing and opening tone holes, and fingering on touch buttons and keys is not easy for children, handicapped persons and old players; a supporting system is combined with the saxophone so as to assist a human player in fingering, and includes sensors, actuators and a controlling unit; while the human player is fingering on the touch buttons and keys, the sensors inform the controlling unit of changes of the depressed touch buttons and depressed keys, and the controlling unit supplies driving signals to the actuators associated with the tone holes to be closed so as to permit the human player easily and quickly to play music tunes.
