ABSTRACT:
A sound reproducing apparatus used in Karaoke and the like uses a record medium or a communication medium on which an accompaniment sound signal, data indicative of a scale, and song standard information are recorded. The sound reproducing apparatus includes a reproducing section, a signal generating section and an adding section. The reproducing section reproduces the accompaniment sound signal and the data indicative of the scale from any of the media. The signal generating section generates a harmony signal relative to a sound signal from a microphone on the basis of the data indicative of the scale reproduced by the reproducing section and the song standard information. The adding section adds the sound signal from the microphone, the accompaniment sound signal reproduced by the reproducing section, and the harmony signal from the signal generating section to produce an output signal.
