[0002] The piano is a keyboard instrument of Western classical music. It has the reputation of "the king of musical instruments". It is composed of keys and metal string soundboards. Roughly the same, they are all equipped with sound boards and many tensioned strings inside the body. The difference is that the hammers of the piano strike the strings, and the harpsichord uses a feather-controlled plectrum to pluck the strings. At present, the piano is More and more people like it. Piano tuning is generally manual operation. The user constantly beats the keys of the piano to determine whether the tuning effect is achieved by changing the sound quality. The patent disclosure of application number CN202022105453.4 Provided is a practical and convenient piano tuning device, specifically related to the field of piano tuning, comprising a frame body, vertical bars are arranged on both sides of the bottom of the frame body, the vertical bars are fixedly connected with the frame body, and the vertical bars The number is two, and the two vertical bars are arranged symmetrically with respect to the central axis in the vertical direction of the frame body. The bottom end of the vertical bar is provided with a fixing plate, and the bottom of one end of the fixing plate is provided with a clamping plate. Compared with the prior art, this device makes piano tuning more convenient to a certain extent by being provided with a tuning rod and a moving rod, but it cannot control the strength of striking the keys, and cannot separately adjust the bass, middle and treble of the piano.
