Claims

[Scope of Claim for Utility Model Registration] A chord data output means for outputting chord data, an external sound detection means for detecting external sound, and a pitch for detecting and outputting the pitch of the external sound signal output by the external sound detection means. detecting means; pitch conversion data output means for creating new pitch data based on the pitch data output by the pitch detection means and the chord data; and based on the new pitch data created by the pitch conversion data output means, a pitch conversion means for converting the pitch of the external audio signal and outputting the same; and mixing and outputting the pitch-converted audio signal outputted by the pitch conversion means and the external audio signal outputted by the external audio output means. An electronic musical instrument characterized by comprising: a mixing means;
