Claims (1)

[Claims for Utility Model Registration] (1) String operation detection means for independently detecting plucking operations on each string strung on a musical instrument body, and a string whose plucking operation is detected by the plucking detecting means. a pitch setting means for setting pitch data corresponding to a fret operation position; and a pitch setting means for determining whether a plurality of strings have been played at the same time based on the detection result of the string operation detection means; If the strings are being plucked, it is further determined whether the pitches specified by the plurality of strings that are plucked at the same time have a specific pitch relationship based on the pitch data set by the pitch setting means. 1. An electronic stringed musical instrument, comprising: pitch determining means for determining a pitch relationship; and sound effect generating means for generating a predetermined sound effect when a specific pitch relationship is determined by the pitch determining means. (2) The electronic stringed instrument according to claim 1, wherein the pitch setting means includes a frett switch that senses a frett operation position for each string. (3) The pitch setting means includes a pickup provided for each string that converts the vibration of the string into an electric signal;
2. The electronic stringed instrument according to claim 1, further comprising pitch extraction means for extracting the pitch of string vibration from the electric signal obtained by said pickup. (4) The apparatus further comprises musical tone generating means for generating a musical tone of a corresponding pitch based on the pitch data set by the pitch setting means. electronic stringed instrument. (5) The sound effect generating means corresponds to one pitch data among the pitch data that determines the specific pitch relationship when it is determined by the pitch determining means that there is a specific pitch relationship. Claim 1, characterized in that the sound effect is generated at a pitch of
The electronic stringed instrument described. (6) A mode for selectively switching between a normal performance mode in which the musical sound generation means generates a musical tone of a predetermined pitch, and a sound effect performance mode in which the sound effect generation means generates a predetermined sound effect. If the pitch determining means determines that a specific pitch relationship exists when the normal performance mode is selected, each pitch data determining the specific pitch relationship is Each musical tone is generated from the musical tone generating means at a corresponding pitch, and when it is determined by the pitch determining means that there is a specific pitch relationship under the condition that the sound effect performance mode is selected, a predetermined pitch is generated. Claim 4 characterized in that the sound effect is generated from the effect generating means.
The electronic stringed instrument described.
