Description

Technical Field

[0001] The utility model relates to the technical field of musical instrument maintenance, in particular to a device for maintaining a keyboard musical instrument. Background Art

[0002] Keyboard instruments are a general term for musical instruments with keys arranged like a piano keyboard. Each key on these instruments has a fixed pitch, so they can be used to play any music within their range. There are often resonance tubes or other resonance devices under the keys. When using keyboard instruments, performers do not directly strike the strings of the instrument to produce vibrations, but use the keys to produce sound through the mechanical mechanisms or electronic components inside the instrument.
