An electronic stringed instrument 1 includes a string-pressing sensor 44 that detects a state of contact between each of a plurality of frets 23 and each of a plurality of strings 22. A CPU 41 detects that picking of any of the plurality of strings 22, provides a sound generation instruction to a connected sound source 45 to produce musical sound of a pitch determined based on the detected state of contact, detects a vibration pitch of the string 22 of which picking was detected, and corrects the pitch of the musical sound generated by the connected sound source 45 based on the detected vibration pitch.
