Keyboard glockenspiel

The keyboard glockenspiel (French: jeu de timbre) is an instrument consisting of a glockenspiel operated by a piano keyboard. It was first used by George Frideric Handel in the oratorio Saul (1739). It was also used in the 1739 revivals of his Il Trionfo del Tempo and Acis and Galatea, and the next year in L'Allegro, il Penseroso ed il Moderato. Half a century later, Wolfgang Amadeus Mozart employed a strumento d’acciaio in The Magic Flute (1791) to represent Papageno's magic bells, and this instrument is believed to have been a keyboard glockenspiel. This part is nowadays sometimes taken by a celesta.Maurice Ravel preferred the keyboard version of the instrument because it can play a true ff dynamic for brilliance and iridescence in orchestral climaxes. In the late 20th century, the firm of Bergerault began manufacturing a three-octave (F2–E4) mallet instrument with a damping mechanism operated by a foot pedal, which is capable of dealing with the wide range called for in contemporary scores.

Musical keyboard

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 Western musical scale, with a combination of larger, longer keys and smaller, shorter keys that repeats at the interval of an octave. Depressing a key on the keyboard causes the instrument to produce sounds, either by causing a hammer to mechanically strike a string or tine (piano, electric piano, clavichord); pluck a string (harpsichord); open a valve to let air flow through a pipe (pipe organ or accordion); or strike a bell (carillon in a church tower). On electric and electronic keyboards, depressing a key connects one or several circuits (Hammond organ, digital piano, synthesizer, MIDI controller keyboard) which causes sounds to be produced. A pedal keyboard is a keyboard used with a pipe organ or theatre organ which is played with the feet. Since the most commonly encountered keyboard instrument is the piano, the keyboard layout is often referred to as the "piano keyboard".

Apple Keyboard

The Apple Keyboard is a keyboard designed by Apple Inc. first for the Apple line, then the Macintosh line of computers. Dozens of models have been released over time, including the Apple Extended Keyboard. There are currently two keyboards offered by Apple: a full-sized version using USB, and the Apple Magic Keyboard, which connects via Bluetooth and omits the numeric keypad of the full-sized model. Both share a similar look and feel, based on a very thin aluminum chassis and laptop-style low-profile keys, sitting much closer to the tabletop than traditional keyboard designs.

Layout

To serve the functionality of the Mac OS (and because of historical differences), the Apple Keyboard's layout differs somewhat from that of the ubiquitous IBM PC keyboard, mainly in its modifier and special keys. Some of these keys have unique symbols defined in the Unicode block Miscellaneous Technical. Features different from other keyboards include:
