The music data is composed of a header, a musical sound track, an effect track, a harmony track, a duet track, a duet video track and the like. In addition to the song title of this song data, the header includes genre data for selecting a background image. The musical sound track is composed of sequence data for producing a karaoke performance sound. The effect track is composed of data for controlling the degree of effects such as echo and reverb applied to the karaoke performance sound formed based on the data of the musical sound track. The harmony track is composed of harmony chorus sequence data corresponding to the karaoke song and formed with a pitch of 3 or 5 degrees with respect to the karaoke song. The duet track is a track provided for a duet song,
It consists of a male part song signal track and a female part song signal track. Since duet songs are often sung alternately by men and women, both tracks do not consist of ADPCM data from the beginning to the end of the song, and the singing part is extracted and made into multiple ADPCM data blocks and paused. A portion is represented by duration data and represented as a sequence of the ADPCM data. The duet video track is a track provided for a duet song and stores the video sequence of the duet singer.

That is, the background image and the singing image of the duet singer are stored in the image controller 15.
One background image is selected based on the genre data of the header. The singing video is output by reproducing the duet singing signal of the other part when only one is sung in the duet song, but at the same time, the image of the singer is read from the image control unit 15 Is played over the background image. Since the singer's video is blocked, it is this duet video track that sequences which blocks to read when.

The sequencer 2 reads the music data having the above configuration. The event data of the musical sound track and the effect track is output to the musical sound forming unit 3, and the event data of the harmony track is output to the harmony chorus forming unit 7. If there is a part that is not sung in the duet song, the event data of the duet track of the part that is not sung is output to the duet song reproduction unit 8. Furthermore, the duet video track of the singer of the part is read out, and the event data is recorded in the image control unit 1.
5 is output. It is assumed that the background image is selected at the start of the karaoke performance and is instructed by the sequencer 2 to the image controller 15.

A harmony chorus sound signal synchronized with the karaoke singing sound signal input from the microphone 10a or the microphone 10b is formed with a pitch based on the harmony track event data input from. In this embodiment, it is possible to form two harmony chorus sounds, that is, a harmony chorus 1 having a third pitch and a harmony chorus 2 having a fifth pitch. The two formed harmony chorus sound signals are output on separate channels,
Each is amplified by the amplifier 4 and then input to the mixer 5.

When only one part (male or female) is singing a duet song, the duet song reproducing section 8 receives a song signal of the other part. The duet song reproduction unit 8 converts this song signal (ADPCM data) into an analog signal and inputs it to the amplifier 4. The amplifier 4 amplifies this signal and then inputs it to the mixer 5.

As described above, the karaoke performance sound signal, the karaoke singing signal, the harmony chorus signal and the duet singing signal are input to the mixer 5. Mixer 5
Assigns these signals to the left and right channels at levels and ratios set individually for each signal, and localizes a sound image at predetermined coordinates. The signals assigned to the left and right channels are added and synthesized for each of the left and right channels and output from the speakers 6 (6L, 6R). The level and ratio of each of the above signals are input from the sound image localization control unit 12.

Further, this karaoke apparatus is provided with a singer sensor 1
