An electronic keyboard (also called digital keyboard, portable keyboard and home keyboard) is an electronic or digital keyboard instrument.
The major components of a typical modern electronic keyboard are:
Musical keyboard: the plastic white and black piano-style keys which the player presses, thus connecting the switches, which triggers the electronic note or other sound. Most keyboards use a keyboard matrix circuit to reduce the amount of wiring that is needed.
User interface software: a program (usually embedded in a computer chip) which handles user interaction with control keys and menus, which allows the user to select tones (e.G., piano, organ, flute, drum kit), effects (reverb, echo, telephones or sustain), and other features (e.G., transposition, an electronic drum machine).
