In a method and apparatus for generating audio-visual musical accompaniment signals corresponding to a musical program, there is provided a recording medium which has an audio storage unit, a lyric storage unit and a video storage unit separate from the audio storage unit and the lyric storage unit. The audio storage unit and the lyric storage unit respectively have a plurality of audio music data and a plurality of lyric data corresponding to a plurality of the musical programs stored therein. The video storage unit has a plurality of video segments to be commonly shared by the plurality of the musical programs stored therein. In operation, the audio music data and the lyric data corresponding to a selected one of the musical programs are retrieved from the recording medium, while at least a section of the video segments are retrieved from the recording medium in an order. The audio music data retrieved from the recording medium is converted into an audio output, and the lyric data and the sections of the video segments retrieved from the recording medium are combined to obtain a video output. The audio and video outputs constitute the musical accompaniment signals corresponding to the selected one of the musical programs.
