Abstract: The present invention relates to an electronic piano including a roll-up keyboard. The roll-up electronic piano comprises a keyboard including piezoelectric material and a controller with a sound chip that controls and amplifies electrical piezoelectric signals. The roll-up electronic piano is easy to carry due to its ultra-light weight and small size. Particularly, the roll-up electronic piano produces a similar tone to that of a real piano. The roll-up electronic piano can be conveniently used in music classes and enhance the efficiency of learning. In addition, the roll-up electronic piano can be played anywhere without being restricted by space and can be controlled by a wireless method.
