Claims

[Scope of Utility Model Registration Claim] The generation of a musical sound of a pitch specified by a pitch specifying means for specifying the pitch of an instrument is controlled by the force of at least one of the breath operation and the lip operation on the mouthpiece. In an electronic wind instrument that instructs a musical sound generating means based on a sense signal obtained by a sensor means that detects the sound as a sense signal, the amount of change in the sense signal obtained by the sensor means at the start of a breath operation per predetermined time a delay time setting means for setting a delay time for the generation of one musical tone with respect to the generation of the other musical tone based on the above; and at least two musical sound waveforms at the pitch specified by the pitch specifying means are set by the delay time setting means. An electronic wind instrument characterized by comprising: musical tone generation control means that controls the musical tone generation means to generate the musical tone continuously at a time interval corresponding to a delay time.
