Claims

[Scope of Utility Model Registration Claim] In an electronic stringed instrument that generates a musical tone of a specified pitch by plucking a plurality of strings that are strung together, a transposition setting means capable of transposing a pitch of a given pitch and setting a plurality of sets of new transposed states; A transposition selection means that can be specified, and when the above set of transposition states is selectively specified during performance by this transposition selection means, the sound of the musical tone generated by the string operation before the selective specification. For high, a musical tone is generated without changing the pitch according to the transposition state set before the selective specification, and the pitch of the musical note to be generated by string operation after the selective specification is as follows. An electronic stringed instrument comprising: control means for controlling the generation of a musical tone at a pitch according to a transposition state set after the selective designation.
