An electronic musical instrument, an electronic or digital derivative of keyboard instruments. Broadly speaking, the term electronic keyboard (or just keyboard or keyboards) can refer to any type of digital or electronic keyboard instrument. These include synthesizers, digital pianos, electronic organs and digital audio workstations. However, an electronic keyboard is more specifically a synthesizer with a built-in low-wattage power amplifier and small loudspeakers.

Electronic keyboards are capable of recreating a wide range of instrument sounds (piano, Hammond organ, pipe organ, violin, etc.) and synthesizer tones with less complex sound synthesis. Electronic keyboards are usually designed for home users, beginners and other non-professional users. They typically have unweighted keys although some more expensive models may have velocity-sensitive keys. Home keyboards typically have little, if any, digital sound editing capacity. The user typically selects from a range of preset 'voices' or sounds, which include imitations of many instruments and some electronic synthesizer sounds. Home keyboards have a much lower cost than professional synthesizers.
