Abstract: Disclosed is a sound generation device including a receiver which receives a sound emission instructing signal in which time data is included and a difference calculator which calculates a difference between a timing indicated in the received time data and a timing when the sound emission instructing signal is received by the receiver, when the sound emission instructing signal in which the time data is included is received. The sound generation device further includes a histogram creator which creates a histogram on the basis of the calculated difference and a difference calculated previously, when the difference is calculated and a timing controller which controls a timing for supplying the received sound emission instructing signal to a sound emission unit on the basis of the calculated difference and a most frequent difference in the created histogram, when the difference is calculated.

Abstract: 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.
