Claims

[Scope of Claim for Utility Model Registration] Pitch setting means provided on the main body of a wind instrument and outputting pitch information for setting a musical tone of a predetermined pitch by fingering operations of a plurality of pitch setting switch means; Breath operation input means for instructing the generation of musical tones at the pitch set by the high setting means by a breath operation on the mouthpiece, and switching for changing the pitch set by the pitch setting means in octave units. An electronic device comprising an octave switching means to be operated, and a musical sound generating means for generating a musical sound instructed by a breath operation of the breath operation input means at a pitch based on pitch information output by the pitch setting means. In a wind instrument, when the fingering operation of a plurality of pitch setting switch means in the pitch setting means changes, after a predetermined first delay time has elapsed from the time of the change, the fingering operation corresponding to the change in the fingering operation is changed. While outputting pitch information to the musical tone generating means, when the switching operation of the octave switching means changes, a second delay time set to a longer time than the first delay time is started from the time of the change. An electronic wind instrument characterized by comprising pitch information output control means for outputting pitch information corresponding to the change in the switching operation to the musical tone generation means after a period of time has elapsed.
