Electronic Keyboards – Their Story and Development

The term "electronic keyboard" refers to an instrument that emits a sound by pressing or showing the keys and in some way uses electricity to facilitate the creation of the sound. Using the electronic keyboard to produce music follows the inevitable evolutionary lines of the first musical keyboard instruments, the tube organ, the clavichord and the harpsichord. The organ of the tube is the oldest, originally developed by the Romans in the 3rd century, and called the hydraulics. The hydraulics produced sound through the reed pipes and were fed by a manual water pump or a natural water source (such as a waterfall).

In ancient Rome, XIV. just keyboard device. Often there was no keyboard, but it operated with large arms or buttons that worked with the whole hand.

The next appearance of clavichord and harpsichord in the 1300s accelerated with the standardization of the 12-tone keyboard. White Natural Keys and Black Sharp / Flat Keys are available on today's keyboards. The popularity of the clavichord and the harpsichord was finally suppressed by the piano's development and widespread spread in the 18th century. The piano was a revolutionary step forward in acoustic music keyboards because a piano player changed the volume (or dynamics) of the sound that was produced by the power of the individual keys.

was the next important step in developing a modern electronic keyboard. The first electrified instrument was believed to be the Denis (built by Vaclav Prokop Dovis), approx. It dates back to 1753. it consisted of over 700 strings that were temporarily electrified to improve their sound quality. Later, a plectra or an electrically activated keyboard was used.

During electrification, neither Denis nor clavecin used power as a sound source. In 1876 Elisha Gray invented the "musical telegraph", which was essentially the first analogue electronic synthesizer. Gray discovered that the self-oscillating electromagnetic circuit could control the sound, and thus invented a basic oscillator. His musical telegraph created a sound from the electromagnetic oscillation of the steel reed and transmitted it over a telephone line. In his later models, Gray continued with a simple loudspeaker consisting of a vibrating membrane in a magnetic field, so he heard a loud oscillator.

Lee De Forrest, self-contained, "Radio Radio", is the next major contributor to electronic keyboard development. In 1906 he invented the triodic electronic valve or the "sound valve". The sound valve was the first termionic valve or "vacuum tube", and De Forrest built the first vacuum tube instrument "Audion Piano" in 1915.

In the 1920s, many new electronic devices were brought to the scene, including Theremin, Ondes Marten and Trautonium

The next big breakthrough in the history of electronic communications. the keyboards were created in 1935 with the introduction of the Hammond organ. Hammond was the first electronic instrument to produce polyphonic sounds and remained until the Chamberlin Music Maker and Mellotron appeared in the late 1940s and early 1950s. Chamberlin and Mellotron were the sampler keyboard for making the first music

The electronic piano first appeared in the 1940s with Rhodes (later Fender Rhodes) "Pre-piano". It is a three and a half-octave instrument made from 1946 to 1948 and equipped with self-amplification. In 1955, Wurlitzer introduced its first electric piano: "A 100."

The rise of musical synthesizers in the 1960s put a strong pressure on the development of today's electronic music keyboards. The first synthesizers were very large, cumbersome machines that were only used in recording studios. The technological development and proliferation of miniaturized solid-state components soon made it possible for manufacturers to be used independently as portable devices in live performances.

It started in 1964 when Bob Moog created the "Moog synthesizer". In the absence of a keyboard, Moog Synthesizer was not really an electronic keyboard. Then in 1970, Moog debuted with "Minimoog", a non-modular synthesizer with built-in keyboard, and this device further standardized the design of electronic music keyboards.

Most early analog synthesizers, such as Minimoog and Roland SH-100, were unanimous, which could produce only one sound at a time. Some, such as EML 101, ARP Odyssey, and Moog Sonic Six, were able to produce two different sounds when two keys were pressed. True polyphony (the production of concurrent sounds that allow chords to play) is only available for the first time using electronic organ models. Many electronic keyboards were created that combined the organic circuits by processing the synthesizer. These included Moog Polymoog, Opus 3, and ARP Omni

Until 1976, further design improvements made it possible for polyphonic synthesizers such as Oberheim Four-Voice, and the Yamaha series CS-50, CS-60. and CS-80. The first truly practical polyphonic synthetic prophet-5 circles introduced in 1977 were. This device was the first to use a microprocessor as a controller and to allow all buttons to be saved in the computer's memory and recalled at the touch of a button. The design of the Prophet-5 soon became a new standard for the electronic keyboard industry.

Accepting a musical instrumental digital interface (MIDI) as a standard for digital code transfer (enabling electronic keyboards to be connected to computers and other devices) and programming), and the ongoing digital technology revolution has made huge progress in electronic keyboard design and implementation , function, sound quality and cost. Today's manufacturers, such as Casio, Yamaha, Korg, Rolland and Kurzweil, now produce lots of well-built, lightweight, versatile, great-sounding and affordable electronic keyboards and will continue to function well in the near future.
