Abstract

The invention belongs to the technical field of piano teaching, and particularly relates to an automatic piano playing teaching device which comprises a piano body and keys installed on the surface of the piano body, a playing box is fixedly connected to the top of the piano body, and a trigger assembly is installed in the playing box. According to the device, a first electromagnet and a second electromagnet are electrified, magnetic repulsion and attraction of magnetic force generated between the first electromagnet and the second electromagnet are controlled, so that a sliding block is pushed to slide on the surface of a sliding rod, and a playing rod is driven by the sliding block to press and separate the surfaces of keys; the piano can automatically press the piano keys according to a song selected by a player to enable the piano body to automatically play, the played song can be conveniently used as teaching guidance, the player can be demonstrated, through display of the display screen, the difference between playing and teaching can be displayed after playing and teaching are finished, and the teaching effect is improved. Therefore, the player can be directly and vividly guided.
