PROBLEM TO BE SOLVED: To suppress delay of generation of musical sound in an electronic stringed instrument.SOLUTION: An electronic guitar has strings having the same thickness and stretched for each string number. In the electronic guitar, a fret scan section detects a contact state between a plurality of frets and between the plurality of strings, and a pitch extraction circuit PC extracts a pitch of a picked string. A microcomputer MCP determines an initial musical interval in accordance with a pressed string state detected by the fret scan section and a picked string detected by the pitch extraction circuit PC and causes a sound source SS to generate musical sound. The microcomputer MCP corrects the extraction result (pitch), extracted by the pitch extraction circuit PC, of the picked string on the basis of correction information stored in a memory and, as sound generated by a string of the string number thereof, changes to musical sound of further exact musical interval. |
