PURPOSE:To enable a person not skilled in singing to correctly sing accompanied with accompaniment, by displaying the timing of song start at the introduction, in singing with the reproduction of an accompaniment tape. CONSTITUTION:In the accompaniment tape 1, the introduction recording part B is normally recorded in greater level than the accompaniment recording part, the DC average level of the output signal of the amplifier 16, the reproducing signal obtained from the magnetic head 4, is greater in reproducing the introduction recording part B than in reproducing the accompaniment recording part C. When the signal level difference like this is used, no detection signal is outputted from the level detector when the introduction is reproduced, but the detection signal is outputted from the level detector 17 when the introduction is finished into the accompaniment. Thus, the drive circuit 18 outputs the drive signal to the song start timing display means 15. |
