RECORDED ORCHESTRAL ACCOMPANIMENT DEVICE

PURPOSE:To display a score together with text and to convert the interval of an instrument performance tone optionally by providing a means which transposes the melody of the scroe according to the set degree of interval conversion and a meams which displays the text and scroe after molody transposition visually and simultaneously. CONSTITUTION:Analog information (b) is impressed to an interval conversion part 3, which converts the interval according to a control signal (c) indicating the degree of interval conversion set by an operation part 4. This conversion part 3 performs fast reproduction or slow reproduction corresponding to the interval conversion by a CCD and a BBD element, and carries out partial insertion or thinning as a time adjustment of playback speed variation. The instrument performance tone (d) converted by the interval conversion part 3 is mixed by a succeeding mixer circuit 5 with an electric signal (c) of singing voice inputted through an external microphone 6 and the mixture signal is sent out to an amplifier part 7 and converted acoustically by a speaker 8. A display conversion control part 10 converts and corrects the chord of the score for transposition and display corresponding to an interval conversion degree control signal (c).
