Timing information which indicates the reproducing timing of the music is buried in the data. Having completed the downloading, the master transfers the music data to portable telephones 2 which become slaves 1 to N respectively using the radio communication modules mounted on the telephones 2. When a chorus is to be performed, information is mutually exchanged via the modules to determine the parts to be played on the telephones 2. The slaves 1 to N start reproducing of the music data by the instruction from the master.
