Strictly speaking, an electronic keyboard is called an electronic musical instrument. To be precise, it is an oscillator made up of electronic circuits that are then processed to produce sound. Electronic keyboards include keyboard keyboards, electric pianos, electronic accordions, performance keyboards (such as electric saxophones), etc.

Electronic keyboards are different from other electroacoustic instruments such as electric guitars, erhus, and violins. Although there are electronic circuits inside these instruments, the electronic circuits only process the vibration signal of the strings. Different from electronic instruments, we call electric guitar, erhu, and violin electroacoustic instruments.

The electronic keyboard is a keyboard instrument, but it is actually an electronic synthesizer. In fact, electronic keyboard is not a correct name at all. Because it looks like a piano, some people call it electronic keyboard. In fact, the official name should be electronic synthesizer.

Using large-scale integrated circuits, most of them are equipped with sound memory (wave table). Used to store the real sound waveforms of various musical instruments and output them during performance. There are two commonly used electronic keyboards: arranger keyboard (with automatic accompaniment) and synthesizer (without automatic accompaniment). In a broad sense, electronic keyboards include electronic pianos (digital pianos, which are different from electroacoustic pianos), which mostly use five-line notation, mostly high and low double-line notation. Alto tablature, simplified notation and guitar tab are sometimes used. Generally used in rock music.
