Electric organ
This article needs additional citations for verification. (August 2009) |
An electric organ, also known as electronic organ, is an electronic keyboard instrument which was derived from the harmonium, pipe organ and theatre organ. Originally designed to imitate their sound, or orchestral sounds, it has since developed into several types of instruments:
- Hammond-style organs used in pop, rock and jazz;
- digital church organs, which imitate pipe organs and are used primarily in churches;
- other types including combo organs, home organs, and software organs.

The immediate predecessor of the electronic organ was the
- Pipe organ
In the 1930s, several manufacturers developed electronic organs designed to imitate the function and sound of pipe organs. At the time, some manufacturers thought that emulation of the pipe organ was the most promising route to take in the development of an electronic organ. Not all agreed, however. Various types of electronic organs have been brought to market over the years, with some establishing solid reputations in their own niche markets.
Early electric organs (1897–1930s)
The use of electricity in organs emerged in the first decades of the 20th century, but it was slow to have a major impact. Electrically powered reed organs appeared during the first decades of electricity, but their tonal qualities remained much the same as the older, foot-pumped models.
Meanwhile, some further experimentation with producing sound by electric impulses was taking place, especially in France.[citation needed]
Tonewheel organs (1930s–1975)
After the failure of the Telharmonium business, similar designs called tonewheel organs were continuously developed; For example:
- Robb Wave Organ by Morse Robb (Canada) — developed since c.1923, marketed 1936–1941[1][2]
- Rangertone by Richard Ranger (United States) — marketed c.1932[3]
- Hammond organ by Laurens Hammond and John M. Hanert[4] (United States) — invented in 1934,[5] marketed 1935[6]–1975 (as the tonewheel organs)
- Lichtton Orgel by Edwin Welte, et al. (Germany) — optical-tonewheel sampling organ, marketed 1935–1940s[7]
One of the earlier electric tonewheel organs was conceived and manufactured by Morse Robb, of the Robb Wave Organ Company. Built in Belleville, Ontario, the Robb Wave Organ predates its much more successful competitor Hammond by patent and manufacture, but shut down its operations in 1938 due to lack of funding.[8]
The first widespread success in this field was a product of the Hammond Clock Company in 1934.[9] The Hammond organ quickly became the successor of the reed organ, displacing it almost completely.
From the start, tonewheel organs operated on a radically different principle from all previous organs. In place of reeds and pipes, Robb and Hammond introduced a set of rapidly spinning magnetic wheels, called
The most revolutionary difference in the Hammond, however, is its huge number of tonewheel settings, achieved by manipulating a system of
The classic Hammond sound benefits from the use of free-standing loudspeakers called tone cabinets. The sound is often further enhanced by rotating speaker units, usually manufactured by Leslie.
The Hammond Organ was widely adopted in popular genres such as
Electrostatic reed organs (1934–1964)
In the wake of Hammond's 1934 invention of the tonewheel organ, competitors explored other possibilities of electric/electronic organ design. Other than the variations of tonewheel organ design, for example, a purely electronic interpretation of the pipe organ (based on "additive synthesis" design) seemed a promising approach. However, it requires a huge number of oscillators, and these circuit scales and complexities were considered a technical bottleneck, as vacuum tube circuits of those days are bulky and unstable. Benjamin Miessner realized that a hybrid approach, using acoustic tone generators along with electronic circuits, could be a reasonable design for commercial products.
The Orgatron was developed in 1934 by Frederick Albert Hoschke, after a Miessner patent.
In 1955, the German company Hohner also released two electrostatic reed organs: the Hohnerola and the Minetta, invented by Ernst Zacharias.[16]
In the same decades, similar electro-acoustic instruments — i.e. electric-fan driven free reed organs with additional electronic circuits — were developed also in Japan.
This type of instrument was later re-commercialized: In 1959, Japanese organ builder, Ichirō Kuroda, built his first Croda Organ with each pair of constantly oscillating free reed and a microphone in the soundproof box, and installed at Nishi-Chiba Church in Chiba Prefecture.[24]
Electronic organs (1930s–)
On the other hand, the Hammond
Electronic organs were once popular home instruments, comparable in price to pianos and frequently sold in department stores. After their début in the 1930s, they captured the public imagination through the recordings of musicians such as Milt Herth (the first performer to record the Hammond Electric Organ) as well as recordings and film performances of Ethel Smith. Nevertheless, they were promoted primarily as church / institutional instruments during the Great Depression and through World War II. After the war, they became more widespread; for example, the Baldwin Piano Company introduced its first in 1946 (with 37 vacuum tubes).[25] Following the adaptation of solid-state electronics to organs in the late 1950s, the market for electronic organs began a fundamental change. Portable electronic keyboards became a regular feature of rock-and-roll music during the 1960s. They are also more convenient to move and store than are the large one-piece organs that had previously defined the market. By the late 1960s, the home organ market was dying while the portable keyboard market was thriving.
Frequency divider organs (1930s–)
Early electronic organ products released in the 1930s and 1940s were already implemented on frequency divider technology using vacuum tubes or transformer-dividers.
With the development of the
Console organs (1930s–)
Console organs, large and expensive electronic organ models, resemble pipe organ consoles. These instruments have a more traditional configuration, including full-range manuals, a wider variety of stops, and a two-octave (or occasionally even a full 32-note) pedalboard easily playable by both feet in standard toe-and-heel fashion. (Console organs having 32-note pedalboards are sometimes known as "concert organs".) Console models, like spinet and chord organs, have internal speakers mounted above the pedals. With their more traditional configuration, greater capabilities, and better performance compared to spinets, console organs are especially suitable for use in small churches, public performance, and even organ instruction. The home musician or student who first learned to play on a console model often found that he or she could later make the transition to a pipe organ in a church setting with relative ease. College music departments made console organs available as practice instruments for students, and church musicians would not uncommonly have them at home.
Home organs (1940s–)
During the period from the 1940s through approximately the 1970s, a variety of more modest self-contained electronic home organs from a variety of manufacturers were popular forms of home entertainment.[26] These instruments were much influenced by theatre organs' sounds and playing style, and often the stops contained imitative voicings such as "trumpet" and "marimba". In the 1950s–1970s, as technology progressed, they increasingly included automated features such as:
- Repeat percussion (Thomas Organ)
- Sustain (Gulbransen[27])
- Glide (Lowrey organ in 1956)[28] — a foot-operated switch temporarily lowers the pitch by about a semitone, to simulate a slide on Hawaiian guitar or trombone.[28][29]
- Chimes stop / Piano stop (Gulbransen[27])
- Vocal chorus (Farfisa Pergamon in 1981)
- Electronic rhythm (Wurlitzer Sideman in 1959, Seeburg & Gulbransen in 1964[27])
- One-touch chords (Hammond S-6 Chord Organ in 1950)
- Automatic Orchestra Control (Lowrey organ in 1963)[28] — turns a single note (on upper manual) into a full chord (designated on lower manual).[30]
- Autochord (Hammond Piper in 1970, Lowrey Magic Genie in c.1975)
- Automatic walking bass (Gulbransen[27])
- Arpeggiator (Hammond organ,[31]etc.)
- Built-in Leslie speaker / Rotary speaker (Gulbransen,[27] Lowrey Holiday Deluxe LSL in 1961,[28] etc.)
and even built-in
While a few such instruments[citation needed] are still sold today, their popularity has waned greatly[citation needed], and many of their functions have been incorporated into more modern and inexpensive portable keyboards.

Spinet organs (1949–)
Following World War II, most electronic home organs were built in a configuration usually called a spinet organ, which first appeared in 1949. These compact and relatively inexpensive instruments became the natural successors to
On spinet organs, the keyboards are typically at least an octave shorter than is normal for organs, with the upper manual (typically 44 notes, F3–C7 in scientific pitch notation) omitting the bass, and the lower manual (typically F2–C6) omitting the treble. The manuals are usually offset, inviting but not requiring the new organist to dedicate the right hand to the upper manual and the left to the lower, rather than using both hands on a single manual. The stops on the upper manual were often 'voiced' somewhat louder or brighter, and user guides encouraged playing the melody on the upper manual and the harmony on the lower. This seemed designed in part to encourage the pianist, who was accustomed to a single keyboard, to make use of both manuals. Stops on such instruments, relatively limited in number, are frequently named after orchestral instruments that they can, at best, only roughly approximate, and are often brightly colored (even more so than those of theatre organs). The spinet organ's loudspeakers, unlike the original Hammond models of the 1930s and 1940s, are housed within the main instrument (behind the kickboard), which saved even more space, although they produce a sound inferior to that of free-standing speakers; some models had jacks for installing external speakers, if desired.
The spinet organ's
Chord organs (1950–)
Shortly after the debut of the spinet, the chord organ appeared.[32] This is an even simpler instrument designed for those who wanted to produce an organ sound in the home without having to learn much organ (or even piano) playing technique. The typical chord organ has only a single manual that is usually an octave shorter than its already-abbreviated spinet counterpart. It also possesses scaled-down registration and no pedalboard. The left hand operates not a keyboard but an array of chord buttons adapted from those of an accordion.
The original Hammond Chord Organs in 1950 are electronic instruments using vacuum-tube technology. In 1958
Transistor organs (1957–)
Electronic organs before the mid-1950s had used vacuum tubes which tended to be bulky and unstable. This restricted attempts to extend features and spread their use into homes. Transistors, invented at Bell Labs in 1947, went into practical production in the 1950s, and their small size and stability led to major changes in the production of electronics equipment, in what has been termed the "transistor revolution".
In 1957, a home organ manufacturer, Gulbransen, introduced the world's first transistor organ, Model B (Model 1100). Although it uses transistors for tone generation, vacuum tubes are still used for amplification.[27] And in 1958, Rodgers built the first fully solid-state transistorized organ for church, called Opus 1 (Model 38).[34] Other manufacturers followed.
Combo organs (1950s–)
By the 1960s, electronic organs were ubiquitous in all genres of popular music, from

Digital organs (1971–)
In 1980, Rodgers introduced the first church organs controlled by microprocessors, partially based on research at the University of Bradford. The university's "Bradford Computing Organ" has technological descendants in some European digital organs using synthesis technology today.
This style of instrument has also been popular with some classically trained concert organists preferring to avoid learning an unfamiliar pipe organ for every concert location, and wishing to perform in venues without pipe organs. Virgil Fox utilized a large Rodgers organ dubbed "Black Beauty" during his Heavy Organ tour during the early 1970s. From 1977 until his death in 1980, he used a custom Allen electronic organ. Carlo Curley toured with a substantial Allen Organ in the US and with an Allen in the UK. Organist Hector Olivera has toured with a custom Rodgers instrument named "The King," and Cameron Carpenter has recently begun touring with a custom 5-manual digital organ by Marshall & Ogletree.[41]
Modern digital organs (1980s–)
Electronic organs are still made for the home market, but they have been largely replaced by the digital keyboard or synthesizer which is smaller and cheaper than typical electronic organs or traditional pianos. Modern digital organs offer features not found in traditional pipe organs, such as orchestral and percussion sounds, a choice of historical pitch standards and temperaments, and advanced console aids.
Digital organs incorporate real-time tone generation based on sampling or synthesis technologies, and may include
The best digital organs of the 2000s incorporate these technical features:
- DSP technology
In 1990, Rodgers introduced
- Sampling
Many digital organs use high-quality samples to produce an accurate sound. Sampled systems may have samples of organ pipe sound for each individual note, or may use only one or a few samples which are then frequency-shifted to generate the equivalent of a 61-note pipe rank. Some digital organs like Walker Technical and the very costly Marshall & Ogletree organs use longer samples for additional realism, rather than having to repeat shorter samples in their generation of sound. Sampling in 2000s-era organs is typically done with 24-bit or 32-bit resolution, at a higher rate than the 44.1
- Surround sound
On most digital organs, several audio channels are used to create a more spacious sound. Higher-quality digital organ builders use custom audio and speaker systems and may provide from 8 to 32 or more independent channels of audio, depending on the size of the organ and the budget for the instrument. With dedicated high-power subwoofers for the lowest frequencies, digital organs can approach the physical sensation of a pipe organ.
- Pipe organ simulations
To better simulate pipe organs, some digital organs emulate changes of
Digital organs may also incorporate simulated models of swell boxes which mimic the environmental effects on pipes, pipe chest valve release, and other pipe organ characteristics. These effects can be included in the sound of modern digital organs to create more realistic pipe organ tone.
Digital pipe sound can include sampled or modeled room acoustics. Rodgers uses binaural and crosstalk cancellation processing to create real-time acoustic models, and Allen also uses room acoustics as part of the sound generation.

Pipe-electronic hybrid organs (1930s–)
Early combinations of pipe organs and electronic technology (including the electronic tone generators, at later) were developed in the 1930s.[43][44] Custom electronic organ consoles occasionally replace aging pipe consoles, updating the electrical control system for the pipes as well as adding electronic voices to the organ. Even large pipe organs are often supplemented with electronic voices for the deepest bass tones that would otherwise require 16- to 32-foot pipes.
For hybrid organs that combine pipes and electronic sounds, pipes change their pitch with environmental changes, but electronic voices do not follow by default. The frequency of sound produced by an organ pipe depends on its geometry and the speed of sound in the air within it. These change slightly with temperature and humidity, so the pitch of an organ pipe will change slightly as the environment changes. The pitch of the electronic portion of a hybrid instrument must be re-tuned as needed. The simplest method is a manual control that the organist can adjust, but some recent digital models can make such adjustments automatically.
Electronic church organs (1939–)
The first full electronic church organ was built in 1939 by Jerome Markowitz, founder of the Allen Organ Company, who had worked for years to perfect the replication of pipe organ sound through the use of oscillator circuitry based on radio tubes. In 1958, Rodgers Organ Company built the first solid-state, transistorized church organ, its three-manual Opus 1.
In contrast to frequency divider circuitry with only a few independent pitch sources, quality electronic church organs have at least one oscillator per note and often additional sets to create a superior ensemble effect. For instance, Rodgers Opus 1 featured eight sets of transistorized pitch generators. Even today, digital organs use software-based digital oscillators to create large numbers of independent pitch and tone sources to better simulate the effect of a large pipe organ.
Digital church organs (1971–)
Digital church organs are designed as pipe organ replacements or as digital consoles to play existing pipes. The differences in sound timbre between piped and digital instruments are debated, but modern digital organs are less expensive and more space efficient.
Digital organs are a viable alternative for churches that may have a pipe organ and can no longer afford to maintain it. Some pipe organs, on the other hand, might be playable without major rebuilding for many decades. However the high initial cost, and longer lead time to design, build, and "voice" pipe organs has limited their production.
Most new digital church organs synthesize sounds from recorded pipe
