Electronic Keyboards – Their History and Development

The term “electronic gaming mechanical keyboard” refers to any instrument that produces sound by the pressing or striking of keys, and uses electricity, in some way, to facilitate the creation of that sound. The use of an electronic keyboard to produce music follows an inevitable evolutionary line from the very first musical keyboard instruments, the pipe organ, clavichord, and harpsichord. The pipe organ is the oldest of these, initially developed by the Romans in the 3rd century B.C., and called the hydraulis. The hydraulis produced sound by forcing air through reed pipes, and was powered by means of a manual water pump or a natural water source such as a waterfall.

From it’s first manifestation in ancient Rome until the 14th century, the organ remained the only keyboard instrument. It often did not feature a keyboard at all, instead utilizing large levers or buttons that were operated by using the whole hand.

The subsequent appearance of the clavichord and harpsichord in the 1300’s was accelerated by the standardization of the 12-tone keyboard of white natural keys and black sharp/flat keys found in all keyboard instruments of today. The popularity of the clavichord and harpsichord was eventually eclipsed by the development and widespread adoption of the piano in the 18th century. The piano was a revolutionary advancement in acoustic musical keyboards because a pianist could vary the volume (or dynamics) of the sound the instrument produced by varying the force with which each key was struck.

The emergence of electronic sound technology in the 18th century was the next essential step in the development of the modern electronic keyboard. The first electrified musical instrument was thought to be the Denis d’or (built by Vaclav Prokop Dovis), dating from about 1753. This was shortly followed by the “clavecin electrique” invented by Jean Baptiste Thillaie de Laborde around 1760. The former instrument consisted of over 700 strings temporarily electrified to enhance their sonic qualities. The later was a keyboard instrument featuring plectra, or picks, that were activated electrically.

While being electrified, neither the Denis d’or or the clavecin used electricity as a sound source. In 1876, Elisha Gray invented such an instrument called the “musical telegraph.,” which was, essentially, the very first analog electronic synthesizer. Gray discovered that he could control sound from a self-vibrating electromagnetic circuit, and so invented a basic single note oscillator. His musical telegraph created sounds from the electromagnetic oscillation of steel reeds and transmitted them over a telephone line. Grey went on to incorporate a simple loudspeaker into his later models which consisted of a diaphragm vibrating in a magnetic field, making the tone oscillator audible.
