Musical keyboard

Common card · No. 231956

A musical keyboard is the set of adjacent depressible levers or keys on a musical instrument. Keyboards typically contain keys for playing the twelve notes of the Chromatic musical scale, with a combination of larger, longer keys and smaller, shorter keys that repeat at the interval of an octave. Pressing a key on the keyboard makes the instrument produce a sound—either by mechanically striking a string or tine (acoustic and electric piano, clavichord), plucking a string (harpsichord), causing air to flow through a pipe (pipe organ), striking a bell (carillon), or activating an electronic circuit (synthesizer, digital piano, electronic keyboard). Since the most commonly encountered keyboard instrument is the piano, the keyboard layout is often referred to as the piano keyboard or simply piano keys.
