Claims (1)

[Scope of Claim for Utility Model Registration] (1) Outputting pitch information specifying the pitch of a musical sound to a musical sound generating means when a breath operation to blow in or a breath operation to inhale is performed;
An electronic wind instrument in which the musical sound generating means generates a musical tone with a pitch corresponding to the pitch information, comprising: a pitch specifying means for specifying the pitch of a single note or the type of chord; and the strength of the blowing operation. A blow-in breath sense means detects the strength of the inhalation operation as a first sense signal; an in-breath breath sense means detects the strength of the inhalation operation to inhale as a second sense signal; The single note of the pitch specified by the pitch specifying means based on either the first sense signal detected by the breath sensing means or the second sense signal detected by the intake breath sense means is An electronic wind instrument comprising: musical tone control means for controlling the musical tone generating means to generate a chord specified by the pitch specifying means based on a sense signal. (2) The pitch designation means has a group of pitch name designation switches that designate a pitch name, and a group of octave designation switches that designates octave information of the pitch name, and when the musical tone control device generates a single note, To generate a chord, set the pitch of the single note to be generated by operating the note name specification switch group and the octave specification switch group, and set the pitch of the root note of the chord by operating the note name specification switch group. 2. The electronic wind instrument according to claim 1, wherein the pitch of each constituent note of the chord is set by setting a high pitch and setting the type of chord by operating the group of octave setting switches. (3) The musical tone control means causes the musical tone generating means to generate a musical tone having a pitch specified by the pitch specifying means when the level value of the first sense signal becomes equal to or higher than a predetermined value. and when the level value of the second sense signal exceeds a predetermined value, the musical tone generating means is controlled to generate a chord specified by the pitch specifying means. The electronic wind instrument according to claim 1 or 2. (4) When a breath operation to breathe in or a breath operation to inhale is performed, pitch information specifying the pitch of a musical tone is output to the musical tone generating means,
The electronic wind instrument generates a musical tone with a pitch corresponding to the pitch information from the musical tone generating means, comprising: a plurality of blowholes for performing a breath operation for blowing in air; and a plurality of intake holes for performing a breath operation for inhaling breath; A blowing air sensor is provided corresponding to each of the blowing holes and detects the strength of the breath blown into each of the blowing holes as a first sense signal; Further, an intake sensor that detects the strength of breath inhaled from each intake hole as a second sense signal, and a sensor that is based on either the first sense signal or the second sense signal. pitch setting means for setting the pitch of a single note; chord setting means for setting a chord based on another sense signal different from the one sense signal; and the pitch set by the pitch setting means. an electronic wind instrument, comprising: a musical tone control means for controlling the musical tone generating means to generate a single note or a chord set by the chord setting means from the musical tone generating means.
