Keyboard instrument is a musical instrument played using a keyboard, a row of levers which are pressed by the fingers. The most common of these are the piano, organ, and various electronic keyboard, including synthesizers and digital pianos. Weighted keys, found on electronic keyboards, are designed to simulate the resistance of a key on an accoustic keyboard, via pressurization, this pressurization may help students transition into accoustic keyboards.

Digital pianos have the full 88 keys of a standard piano keyboard, and most workstations have at least 61 keys or more. Lower-end synthesizers may have as few as 25 keys, although most home-use keyboards come with 49, 61, or 76 keys.
