    Abstract: PURPOSE: A digital piano on which a touch screen is mounted and an operating method thereof are provided to display digital music corresponding to a recognized play scale on the touch screen and automatically turn a page over according to a playing part. CONSTITUTION: A recognition unit(120) recognizes a sound source input signal which is inputted by a keyboard. A sound source processing unit(170) recalls a stored digital sound source according to the sound source input signal. The sound source processing unit converts the digital sound source into an analog sound source. An output unit(130) outputs the analog sound source through a speaker. A touch screen(150) displays a playing part in real time based on the screen of a digital music and the sound source input signal.
