Abstract
The electronic musical instrument includes a detecting unit, an excitation signal generator and a tone generator. The detecting unit detects body action to produce an action signal representative of the detected body action. The detecting unit includes a sensor element directly attached to a given part of a player's body for detecting the body action of that part. The excitation signal generator produces an excitation signal according to the action signal. The tone generator is one of a delayed feedback type, receives the excitation signal, and generates a musical tone signal according to a designated tone pitch. The tone generator includes a delay element for delaying the excitation signal by a given time corresponding to the designated tone pitch, and a feedback path for feeding back the delayed excitation signal to the delay element.
