1. An electronic musical instrument comprising:
- a microphone for converting an externally input voice into an electrical signal;
a memory circuit for storing a series of pitch shift data for shifting a tone pitch of the externally input voice signal output from said microphone;
a data readout circuit for sequentially reading out the series of pitch shift data from said memory circuit every time an operation switch means is operated; and
tone pitch converting means for shifting the tone pitch of the externally input voice signal supplied from said microphone on the basis of the series of pitch shift data supplied from said memory circuit, and outputting the shifted externally input voice signal.

Abstract
This invention discloses an electronic musical instrument, which shifts the tone pitches of a series of externally input voice signals in real time, and outputs the shifted voice signals from a loudspeaker. Data for shifting the tone pitches of voice signals is pre-programmed in a memory circuit as music piece data. Every time a user operates an operation switch, the music piece data is sequentially read out, and the tone pitches of voice signals input from a microphone are shifted by a tone pitch converter. The shifted voice signals are output from a loudspeaker in real time. The input voice signals can be shifted to a melody corresponding to the music piece data.

7. A method of controlling a pitch of an externally input voice, comprising the steps of:
-
(a) converting the externally input voice to an input voice signal; (b) determining if an operation switch of an electronic musical instrument has been activated; (c) reading music piece data from a memory when the operation switch is activated in said step (b); (d) shifting the pitch of the input voice signal according to the music piece data read in said step (c); and (e) outputting the shifted input voice signal. - View Dependent Claims (8, 9, 10, 11, 12)
