Electronic keyboard
Résumé
An electronic keyboard, portable keyboard, or digital keyboard is an electronic musical instrument based on keyboard instruments. Electronic keyboards include synthesizers, digital pianos, stage pianos, electronic organs and digital audio workstations. In technical terms, an electronic keyboard is a synthesizer with a 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. The least expensive models do not have velocity-sensitive keys, but mid- to high-priced models do. 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. Casio and Yamaha are among the leading manufacturers of home keyboards, with Casio popularizing the instrument since the 1980s with their Casiotone lineup.
An electronic keyboard may also be called a digital keyboard, or home keyboard, the latter often refers to less advanced or inexpensive models intended for beginners. The obscure term "portable organ" was widely used in Asian countries to refer to electronic keyboards in the 1990s, due to the similar features between electronic keyboards and electronic home organs, the latter of which were popular in the late 20th century.
In Russia, Belarus and Ukraine, most types of electronic keyboards (including digital pianos and stage pianos) were simply often referred to as a "synthesizer" (Russian: синтезатор, sintezator), usually with no other term to distinguish them from actual digital synthesizers.
