Electronic organ is an electronic keyboard instrument, belonging to the electronic synthesizer.
It uses large - scale integrated circuits, most of the configuration of sound memory memory (wave table). Used to store the real sound waveform of various instruments and output it when playing. Commonly used electronic keyboard arrangement keyboard (with automatic accompaniment) and synthesizer (without automatic accompaniment) two categories, the broad sense of electronic piano including electronic piano (digital piano, different from electroacoustic piano), more use of staff, more for high and low double line notation. Sometimes also use alto spectrum and simple spectrum, guitar spectrum. Generally used of rock music.
