CONSTITUTION:The user reproduces a disk for orchestral accompanyment by a disk reproducing means 1 and a playing music signal is sent to an amplifier means 4 via a key conversion means 2. On the other hand, a voice is inputted from a voice input means 5 comprising a microphone or the like to sing a song accompanied with the playing music signal, the result is mixed and amplified by the amplification means 4 and connected to a loudspeaker from a signal output terminal 6 and loudspoken to enjoy singing with the orchestral accompanyment. A control storage means 3 has a function registering an optimum key data to each music of each disk by the user and discriminates the reproduced disk automatically when the key data is once registered and sets an optimum key automatically to the user to a music to be played.
