Electronic Keyboards – Their History and Development


The time period “electronic keyboard” refers to any device that produces sound by way of the pressing or putting of keys, and makes use of power, in a few way, to facilitate the creation of that sound. The use of an electronic keyboard to provide song follows an inevitable evolutionary line from the very first musical keyboard contraptions, the pipe organ, clavichord, and harpsichord. The pipe organ is the oldest of those, to start with advanced by means of the Romans within the 3rd century B.C., and referred to as the hydraulis. The hydraulis produced sound through forcing air through reed pipes, and turned into powered by using a manual water pump or a natural water source consisting of a waterfall.

From it’s first manifestation in ancient Rome until the 14th century, the organ remained the handiest keyboard tool. It often did not feature a keyboard in any respect, rather making use of big levers or buttons that have been operated with the aid of the use of the complete hand.

The subsequent look of the clavichord and harpsichord inside the 1300’s changed into increased by using the standardization of the 12-tone keyboard of white herbal keys and black sharp/flat keys discovered in all keyboard gadgets of today. The popularity of the clavichord and harpsichord was eventually eclipsed via the development and massive adoption of the piano within the 18th century. The piano became a innovative advancement in acoustic musical keyboards due to the fact a pianist ought to range the volume (or dynamics) of the sound the instrument produced via various the force with which every key changed into struck.

The emergence of digital sound era inside the 18th century was the next essential step within the improvement of the cutting-edge digital keyboard. The first electrified musical device turned into concept to be the Denis d’or (constructed by way of Vaclav Prokop Dovis), courting from approximately 1753. This become rapidly followed via the “clavecin electrique” invented with the aid of Jean Baptiste Thillaie de Laborde round 1760. The former device consisted of over seven hundred strings briefly electrified to beautify their sonic characteristics. The later changed into a keyboard instrument offering plectra, or alternatives, that have been activated electrically.

While being electrified, neither the Denis d’or or the clavecin used electricity as a valid supply. In 1876, Elisha Gray invented such an instrument referred to as the “musical telegraph.,” which changed into, essentially, the first actual analog electronic synthesizer. Gray located that he may want to control sound from a self-vibrating electromagnetic circuit, and so invented a basic single notice oscillator. His musical telegraph created sounds from the electromagnetic oscillation of steel reeds and transmitted them over a cellphone line. Grey went directly to incorporate a simple loudspeaker into his later models which consisted of a diaphragm vibrating in a magnetic subject, making the tone oscillator audible.

Lee De Forrest, the self-styled “Father Of Radio,” become the next most important contributor to the improvement of the electronic keyboard. In 1906 he invented the triode electronic valve or “audion valve.” The audion valve turned into the primary thermionic valve or “vacuum tube,” and De Forrest constructed the first vacuum tube tool, the “Audion Piano,” in 1915. The vacuum tube became an essential component of electronic units for the subsequent 50 years till the emergence and big adoption of transistor generation.

The decade of the 1920’s delivered a wealth of new digital units onto the scene inclusive of the Theremin, the Ondes Martenot, and the Trautonium.

The next fundamental step forward within the records of electronic keyboards got here in 1935 with the advent of the Hammond Organ. The Hammond changed into the first digital tool capable of producing polyphonic sounds, and remained so till the discovery of the Chamberlin Music Maker, and the Mellotron within the overdue 1940’s and early 1950’s. The Chamberlin and the Mellotron were the first ever sample-playback keyboards meant for making song.

The digital piano made it is first appearance inside the 1940’s with the “Pre-Piano” with the aid of Rhodes (later Fender Rhodes). This changed into a three and a half octave tool crafted from 1946 until 1948 that came prepared with self-amplification. In 1955 the Wurlitzer Company debuted their first electric powered piano, “The a hundred.”
