PURPOSE:To distribute desired music information to a user within an extremely short time by providing an electronic computer, a music data file in which many melodies have been recorded in the form of music information which has encoded various sheet music symbols, a storage device, and a printer, on a master station. CONSTITUTION:A slave station can display list information of melodies held by a master station by only operating an input device 13, when it is stored in a storage device 14, and sends a signal to the master station, unless it is stored in the storage device 14 and list information is transfered to the slave station storage device 14 from a master station storage device 7. The slave station gives an arranging number of a desired melody to the input device 13. In response to the request, the master station accumulates the number of times of a musical performance of every melody at each slave station based on information 26, stores its accumulated value in the storage device 7, and on the other hand, sends back the information group to the slave station. In the slave station, when a desired melody stored in a data file 12 is designated by operating the input device 13, music information of its melody is converted to performance information by an electronic computer 11. |
