Abstract
An electronic wind instrument is provided with a processor (CPU) and plural touch sensors (a detecting unitand detecting units) 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) 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) 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.
