Abstract: A music playback device applicable to a portable telephone terminal device uses a sequence data FIFO memory and a waveform data FIFO memory both having limited storage capacities. A system CPU performs successive transfer of sequence data and waveform data in response to shortage events of the memories. Hence, it is possible to actualize high-quality playback of musical tunes with small storage capacities of the memories and with small load of processing of the system CPU.

Abstract: There is provided a novel music data compression method which is capable of significantly reducing the size of music data. Music data including a sequence of performance event data each formed of note information is received. Each of the pieces of performance event information of the music data is converted to another form of performance event information including status information corresponding to a matching or mismatching pattern in note information between the piece of performance event information and an immediately preceding one of the pieces of performance event information, and note information necessitated according to the matching or mismatching pattern to which the status information corresponds.
