A 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 keyboards, including synthesizers and digital pianos. Other keyboard instruments include celestas, which are struck idiophones operated by a keyboard, and carillons, which are usually housed in bell towers or belfries of churches or municipal buildings.[1]

Today, the term keyboard often refers to keyboard-style synthesizers. Under the fingers of a sensitive performer, the keyboard may also be used to control dynamics, phrasing, shading, articulation, and other elements of expression—depending on the design and inherent capabilities of the instrument.[1]

Another important use of the word keyboard is in historical musicology, where it means an instrument whose identity cannot be firmly established. Particularly in the 18th century, the harpsichord, the clavichord, and the early piano competed, and the same piece might be played on more than one. Hence, in a phrase such as "Mozart excelled as a keyboard player," the word keyboard is typically all-inclusive.

The term keyboard classifies instruments based on how the performer plays the instrument, and not on how the sound is produced. Categories of keyboard instruments include the following families (of which this is only a partial list):

The earliest known keyboard instrument was the Ancient Greek hydraulis, a type of pipe organ, invented in the third century BC.[2] The keys were likely balanced and could be played with a light touch, as is clear from the reference in a Latin poem by Claudian (late 4th century), who says magna levi detrudens murmura tactu . . . intonet, that is “let him thunder forth as he presses out mighty roarings with a light touch” (Paneg. Manlio Theodoro, 320–22). From its invention until the fourteenth century, the organ remained the only keyboard instrument. Often, the organ did not feature a keyboard at all, but rather buttons or large levers operated by a whole hand. Almost every keyboard until the fifteenth century had seven naturals to each octave.[3]

The clavicymbalum, clavichord, and the harpsichord appeared during the fourteenth century—the clavichord probably being earlier. The harpsichord and clavichord were both common until the widespread adoption of the piano in the eighteenth century, after which their popularity decreased. The first template to the modern piano was introduced in 1698 in Italy by Bartolomeo Cristofori as the gravicèmbalo con piano e forte ("harpsichord with soft and loud"), also shortened to pianoforte, as it allowed the pianist to control the dynamics by adjusting the force with which each key was struck. In its current form, the piano is a product of further developments made since the late nineteenth century and is distinct in both sound and appearance from the instruments known to earlier pianists, including Mozart, Haydn, and Beethoven.[1] Beginning in the twentieth century, early electromechanical instruments, such as the Ondes Martenot, began to appear as well.[4]

Modern keyboards[edit]

Much effort has gone into creating an instrument that sounds like the piano but lacks its size and weight. The electric piano and electronic piano were early efforts that, while useful instruments in their own right, did not convincingly reproduce the timbre of the piano.[5][6] Electric and electronic organs were developed during the same period. More recent electronic keyboard designs strive to emulate the sound of specific make and model pianos using digital samples and computer models. Each acoustic keyboard contains 88 keys; however, smaller arrangements have a minimum of 61 keys.[7]

Types of keyboard action[edit]

A simple keyboard has light plastic keys with springs that return them to their initial position after being played. The action of such a keyboard is similar to the feel of an acoustic organ. Weighted keys are designed to simulate the resistance of a key on an acoustic piano keyboard.
