PURPOSE: A method for making a digital music file which is free to move by a division unit is provided to freely move to a desired bar during playing a music by separately inserting the data to a corresponding index after diving the music by a bar unit. CONSTITUTION: The system includes a controller(10), a display output device(20), an input device(30), a midi interface(40), an amplifier(50) and a speaker(60). The controller controls an output of electronic score by connecting to the display output device and processes an input signal of input device through the midi interface. The display output device outputs a midi file into an electronic score format and outputs a background image and words. The input device is an electronic instrument supporting midi, a keyboard, a mouse, a joy pad and so on. The midi interface connects to the controller and input device, converts the playing signal of input device into a digital signal and transmits the converted signal to the controller. The midi interface is equipped with a sound source module including a sound generating circuit by the synthesizing and sampling techniques. The sound from the sound source module is amplified by the amplifier and outputted through the speaker.
