Abstract: An electronic wind instrument is provided with a processor (CPU 5) and plural touch sensors (a detecting unit 12s and detecting units 13s) disposed along a first direction. A first output variable da/dt is obtained, representing a variation per unit time of an output value from a first sensor (detecting unit 12s) in the plural touch sensors disposed on the side close to first end (tip side) in the first direction. A second output variable dS/dt is obtained, representing a variation per unit time of a sum of output values from second sensors (detecting units 13s) disposed between a second end (heel side) and the first sensor in the first direction. The processor judges based on the first output variable da/dt and the second output variable dS/dt whether a tonging process should be performed.

Abstract: An electronic musical instrument uses a mouthpiece model that models a mouthpiece as a three-dimensional shape having one end at which the mouthpiece is to be held in a mouth of a performer being smaller than another end. A processor in the instrument calculates a reflection coefficient of a progressive wave and a regressive wave using the mouthpiece model by calculating a wave impedance for the progressive wave and calculating a wave impedance for the regressive wave, and generates a musical sound signal on the basis of the calculated reflection coefficient, which is then outputted to a sound generator for sound production.
