Keyboard instrument is the general name of instruments with keys arranged like 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 devices for resonance under the keys.

The sound principle of the electric piano is to use the keyboard as the on-off switch to form an electric pulse. Once the key is pressed, the internal crystal oscillator starts to work, forming a pulse to generate a certain frequency waveform, and then it is amplified by the frequency divider and sent to the speaker for sound. The whole sound production process depends on a simple frequency division analog circuit, so the keyboard has no force and string feeling, and the sound is relatively mechanical and monotonous.
