PURPOSE:To know and utilize the frequencies of performance by numbers as reference information by storing a storage means with the frequencies of performance by the numbers and displaying them on a display means. CONSTITUTION:A music data storage device 1 stored with music data, a performance frequency storage device 2 stored with the frequencies of performance by the numbers, an input device 4 for specifying a number to be played, a microphone 7 for inputting a singing voice, a video reproduction device 5 which reproduces video data of music data and outputs it to a monitor 8, and a voice reproduction device 6 which reproduces the voice data of the music data and outputs the data to a speaker 9 together with the sound from the microphone 7 are connected to a controller 3 as a control means. Then the performance frequency storage device 2 is stored with the frequencies of performance by the numbers and the stored frequencies of performance are displayed on the monitor 8. Consequently, the frequencies of performance by the numbers can be known and utilized for service or as the reference information when music data which is small in performance frequency is erased. |
