keyboards, the two manuals are positioned on two levels close to each other. Each is laid out in a similar manner to a piano keyboard, except that pressing a key on a Hammond results in the sound continuously playing until it is released, whereas with a piano, the note's volume decays. No difference in volume occurs regardless of how heavily or lightly the key is pressed (unlike with a piano), so overall volume is controlled by a pedal (also known as a "swell" or "expression" pedal).

, which allows players to perform rapid passages more easily than on a piano. In contrast to piano and pipe organ keys, Hammond keys have a flat-front profile, commonly referred to as "waterfall" style. Early Hammond console models had sharp edges, but starting with the B-2, these were rounded, as they were cheaper to manufacture. The M series of spinets also had waterfall keys (which has subsequently made them ideal for spares on B-3s and C-3s), but later spinet models had "diving board" style keys which resembled those found on a church organ. Modern Hammond-Suzuki models use waterfall keys. Hammond console organs come with a wooden pedalboard played with the feet, for bass notes. Most console Hammond pedalboards have 25 notes, with the bottom note a low C and the top note a

Drawbars

The sound on a tonewheel Hammond organ is varied through the manipulation of drawbars. A drawbar is a metal slider that controls the volume of a particular sound component, in a similar way to a fader on an audio mixing console. As a drawbar is incrementally pulled out, it increases the volume of its sound. When pushed all the way in, the volume is decreased to zero. The labeling of the drawbar derives from the stop system in pipe organs, in which the physical length of the pipe corresponds to the pitch produced. Most Hammonds contain nine drawbars per manual. The drawbar marked "8′" generates the fundamental of the note being played, the drawbar marked "16′" is an octave below, and the drawbars marked "4′", "2′" and "1′" are one, two and three octaves above, respectively. The other drawbars generate various other
harmonics In physics, acoustics, and telecommunications, a harmonic is a sinusoidal wave with a frequency that is a positive integer multiple of the ''fundamental frequency'' of a periodic signal. The fundamental frequency is also called the ''1st harm ...

of the note. While each individual drawbar generates a relatively pure sound similar to a flute or electronic oscillator, more complex sounds can be created by mixing the drawbars in varying amounts. Because of this, the Hammond organ can be considered a type of

. Hammond manufactured from 1969 onwards have the footage of each drawbar engraved on its end. Some drawbar settings have become well-known and associated with certain musicians. A very popular setting is 888000000 (i.e., with the drawbars labeled "16′", "′" and "8′" fully pulled out), and has been identified as the "classic" Jimmy Smith sound.


Presets

In addition to drawbars, many Hammond tonewheel organ models also include presets, which make predefined drawbar combinations available at the press of a button. Console organs have one octave of reverse colored keys (naturals are black, sharps and flats are white) to the left of each manual, with each key activating a preset; the far left key (C), also known as the cancel key, de-activates all presets, and results in no sound coming from that manual. The two right-most preset keys (B and B) activate the corresponding set of drawbars for that manual, while the other preset keys produce preselected drawbar settings that are internally wired into the preset panel.


Vibrato and chorus

Hammond organs have a built-in

where a note's sound is combined with another sound at a slightly different and varying pitch. The best known vibrato and chorus system consists of six settings, V1, V2, V3, C1, C2 and C3 (i.e., three each of vibrato and chorus), which can be selected via a rotary switch. Vibrato / chorus can be selected for each manual independently.


Harmonic percussion

The B-3 and C-3 models introduced the concept of "Harmonic Percussion", which was designed to emulate the percussive sounds of the
harp The harp is a stringed musical instrument that has individual strings running at an angle to its soundboard; the strings are plucked with the fingers. Harps can be made and played in various ways, standing or sitting, and in orchestras or ...

when a key is pressed. The selected percussion harmonic fades out, leaving the sustained tones the player selected with the drawbars. The volume of this percussive effect is selectable as either normal or soft. Harmonic Percussion retriggers only after all notes have been released, so legato passages sound the effect only on the first note or chord, making Harmonic Percussion uniquely a "single-trigger", but still a polyphonic effect.


Start and run switches

Before a Hammond organ can produce sound, the motor that drives the tonewheels must come up to speed. On most models, starting a Hammond organ involves two switches. The "Start" switch turns a dedicated
starter motor A starter (also self-starter, cranking motor, or starter motor) is a device used to rotate (crank) an internal-combustion engine so as to initiate the engine's operation under its own power. Starters can be electric, pneumatic, or hydraulic. T ...
, which must run for about 12 seconds. Then, the "Run" switch is turned on for about four seconds. The "Start" switch is then released, whereupon the organ is ready to generate sound. The H-100 and E-series consoles and L-100 and T-100 spinet organs, however, had a self-starting motor that required only a single "On" switch. A pitch bend effect can be created on the Hammond organ by turning the "Run" switch off and on again. This briefly cuts power to the generators, causing them to run at a slower pace and generate a lower pitch for a short time. Hammond's New B3 contains similar switches to emulate this effect, though it is a digital instrument.

, to help him achieve the desired organ sound. To cut costs, Hammond made a pedalboard with only 25 notes, instead of the standard 32 on church organs, and it quickly became a ''de facto'' standard. On April 24, 1934, Hammond filed a patent for an "electrical musical instrument", which was personally delivered to the patent office by Hanert, the co-inventor, explaining that they could start production immediately and it would be good for local employment in Chicago. The invention was unveiled to the public in April 1935, and the first model, the Model A, was made available in June of that year. Over 1,750 churches purchased a Hammond organ in the first three years of production, and by the end of the 1930s, over 200 instruments were being made each month. By 1966, an estimated 50,000 churches had installed a Hammond. For all its subsequent success with professional musicians, the original company did not target its products at that market, principally because Hammond did not think there would be a sufficient return. In 1936, the

. During the auditory tests, sustained tones and excerpts from musical works were played on the electric and pipe organs while a group of musicians and laymen attempted to distinguish between the instruments. While attorneys for Hammond argued that the test listeners were wrong or guessed nearly half the time, witnesses for the FTC claimed that Hammond employees had unfairly manipulated the Skinner organ to sound more like the Hammond. In 1938, the FTC ordered Hammond to "cease and desist" a number of advertising claims, including that its instrument was equivalent to a $10,000 pipe organ. After the FTC's decision, Hammond claimed that the hearings had vindicated his company's assertions that the organ produced "real", "fine", and "beautiful" music, phrases which were each cited in the FTC's original complaint, but not included in the "cease and desist" order. Hammond also claimed that although the hearing was expensive for his company, the proceedings generated so much publicity that "as a result we sold enough extra organs to cover the expense." The Hammond Organ Company produced an estimated two million instruments in its lifetime; these have been described as "probably the most successful electronic organs ever made". A key ingredient to the Hammond organ's success was the use of dealerships and a sense of community. Several dedicated organ dealers set up business in the United States and there was a bi-monthly newsletter, ''The Hammond Times'', mailed out to subscribers. Advertisements tended to show families gathered around the instrument, often with a child playing it, as an attempt to show the organ as a center-point of home life and to encourage children to learn music.

or speakers, so a special external ''keyboard'' amplifier and speaker cabinet is required. * Spinet organs have two 44-note manuals and one octave of pedals, plus an internal power amplifier and set of speakers.


Console organs

The first model in production, in June 1935, was the Model A. It contained most of the features that came to be standard on all console Hammonds, including two 61-key manuals, a 25-key pedalboard, an expression pedal, 12 reverse-color preset keys, and one for the pedals. To address concerns that the sound of the Hammond was not rich enough to accurately mimic a pipe organ, the model BC was introduced in December 1936. It included a chorus generator, in which a second tonewheel system added slightly sharp or flat tones to the overall sound of each note. The cabinet was made deeper to accommodate this. Production of the old Model A cases stopped, but the older model continued to be available as the AB until October 1938. A model BA of 1938 may be seen and heard at the Musical Museum, Brentford England. Criticism that the Hammond organ was more aesthetically suitable to the home instead of the church led to the introduction of the model C in September 1939. It contained the same internals as the AB or BC, but covered on the front and sides by "modesty panels" to cover female organists' legs while playing in a skirt, often a consideration when a church organ was placed in front of the congregation. The model C did not contain the chorus generator, but had space in the cabinet for it to be fitted. The concurrent model D was a model C with a prefitted chorus. Development of the vibrato system took place during the early 1940s, and was put into production shortly after the end of

. The various models available were the BV and CV (vibrato only) and BCV and DV (vibrato and chorus). The B-2 and C-2, introduced in 1949, allowed vibrato to be enabled or disabled on each manual separately. In 1954, the B-3 and C-3 models were introduced with the additional harmonic percussion feature, advertised as "touch response percussion control". Despite several attempts by Hammond to replace them, these two models remained popular and stayed in continuous production through early 1975. The last B-3 and C-3 organs manufactured were built from leftover parts, and are not considered as good as earlier models. To cater more specifically to the church market, Hammond introduced the Concert Model E in July 1937, which included a full 32-note pedalboard and four electric switches known as toe pistons, allowing various sounds to be selected by the feet. The model E was replaced by the model RT in 1949, which retained the full-sized pedalboard, but otherwise was internally identical to the B and C models. RT-2 and RT-3 models subsequently appeared in line with the B-2/C-2 and B-3/C-3, respectively. In 1959, Hammond introduced the A-100 series. It was effectively a self-contained version of the B-3/C-3, with an internal power amplifier and speakers. The organ was manufactured in a variety of different chassis, with the last two digits of the specific model number determining the style and finish of the instrument. For example, A-105 was "Tudor styling in light oak or walnut", while the A-143 was "warm cherry finish, Early American styling". This model numbering scheme was used for several other series of console and spinet organs that subsequently appeared. The D-100 series, which provided a self-contained version of the RT-3, followed in 1963. The E-100 series was a cost-reduced version of the A-100 introduced in 1965, with only one set of drawbars per manual, a reduced number of presets, and a slightly different tone generator. This was followed by the H-100 series, with a redesigned tonewheel generator and various other additional features. An extended model, the H-300, also featured an integrated

. The organ was not particularly well made, and suffered a reputation for being unreliable. Hammond service engineer Harvey Olsen said, "When they -100swork, they sound pretty decent. But die-hard enthusiasts won't touch it."


Spinet organs

Though the instrument had been originally designed for use in a church, Hammond realized that the amateur home market was a far more lucrative business, and started manufacturing spinet organs in the late 1940s. Outside of the United States, they were manufactured in greater numbers than the consoles, and hence were more widely used. Several different types of M series instruments were produced between 1948 and 1964; they contained two 44-note manuals with one set of drawbars each, and a 12-note pedalboard. The M model was produced from 1948 to 1951, the M-2 from 1951 to 1955, and the M-3 from 1955 to 1964. The M series was replaced by the M-100 series in 1961, which used a numbering system to identify the body style and finish as used on earlier console series. It included the same manuals as the M, but increased the pedalboard size to 13 notes, stretching a full octave, and included a number of presets. The L-100 series entered production at the same time as the M-100. It was an economy version, with various cost-cutting changes so the organ could retail for under $1,000. The vibrato was a simpler circuit than on other consoles and spinets. Two variations of the vibrato were provided, plus a chorus that mixed various vibrato signals together. The expression pedal, based on a cheaper design, was not as sophisticated as on the other organs. The L-100 sold particularly well in the UK, with several notable British musicians using it instead of a B-3 or C-3. The T series, produced from 1968 to 1975, was the last of the tonewheel spinet organs. Unlike all the earlier Hammond organs, which used

Transistor organs

In the 1960s, Hammond began to manufacture transistor organs in response to competitors such as Lowrey and

. It contained separate "vibrato bass" and "vibrato treble" in an attempt to simulate a Leslie speaker. Hammond designed it as the company's flagship product, in response to market competition and to replace the B-3. However, it was considered expensive at $9,795 and it sold poorly. It did not sound like a B-3. Hammond introduced their first

(IC) model, the Concorde, in 1971. The company had stopped manufacturing tonewheel organs entirely by 1975, due to increased financial inefficiency, and switched to making IC models full-time. Console models included the 8000 Aurora (1976) and 8000M Aurora (1977), which contained drawbars and a built-in rotating speaker. Spinet organs included the K-100 and J-400 series, and the "Cadette" V series. Some models included a

. The B-3 and C-3 were replaced by the B-3000, designed to be a model for professional use that had the same look and feel of the earlier organs. It contained the same controls, but was lighter than a B-3. Although promoted by Hammond as a suitable replacement, musicians did not think it had a comparable sound. In 1979, a Japanese offshoot, Nihon Hammond (literally meaning 'Japan Hammond'), introduced the X-5, a portable solid-state clone of the B-3. Though transistor Hammonds were criticised for their sound, the company remained commercially successful. Many such models were sold to churches, funeral homes and private residences.


Hammond-Suzuki

, did not believe it was practical to move Hammond's manufacturing operation from the US to Japan, and viewed Hammond's declining sales figures as a problem. Laurens Hammond died in 1973. In 1985, Hammond went out of business, though servicing and spares continued to be available under the name of the Organ Service Company. In early 1986, the Hammond brand and rights were acquired by Hammond Organ Australia, run by Noel Crabbe. Then in 1989, the name was purchased by the Suzuki Musical Instrument Corporation, which rebranded the company as Hammond-Suzuki. Although nominally a Japanese company, founder Manji Suzuki was a fan of the instrument and retained several former Hammond Organ Company staff for research and development, and ensured that production would partially remain in the United States. The new company produced their own brand of portable organs, including the XB-2, XB-3 and XB-5. ''

'' Rod Spark, a longtime Hammond enthusiast, said these models were "a matter of taste, of course, but I don't think they're a patch on the old ones". In 2002, Hammond-Suzuki launched the New B-3, a recreation of the original electromechanical instrument using contemporary electronics and a digital tonewheel simulator. The New B-3 is constructed to appear like the original B-3, and the designers attempted to retain the subtle nuances of the familiar B-3 sound. Hammond-Suzuki promotional material states that it would be difficult for even an experienced B-3 player to distinguish between the old and new B-3 organs. A review of the New B-3 by Hugh Robjohns called it "a true replica of an original B-3 ... in terms of the look and layout, and the actual sound". The instrument project nearly stalled after a breakdown in negotiations between Japanese and United States staff, the latter of whom insisted on manufacturing the case in the United States and designing the organ to identical specifications to the original. The company has since released the XK-3, a single-manual organ using the same digital tonewheel technology as the New B-3. The XK-3 is part of a modular system that allows an integrated lower manual and pedals to be added. In response to some clones, including a variety of vintage keyboards in a single package, Hammond released the SK series of organs, which include

'' magazine's Stephen Fortner praised the single manual SK1, indicated that it gave an accurate sound throughout the range of drawbar settings, and said the organ sound was "fat, warm, utterly authentic". The XK-1c model was introduced in early 2014, which is simply an organ-only version of the SK1. An updated flagship organ, the XK-5, was launched in 2016, and a stage keyboard, the SK-X followed in 2019, which allows a player to select an individual instrument (organ, piano or synthesizer) for each manual. In the US, Hammond manufactures a number of dedicated console organs, including the B-3mk2 and the C-3mk2, and the A-405, a Chapel Console Organ. The company has a dedicated Church Advisory Team that provides a consultancy, so churches can choose the most appropriate instrument.

eration to a Hammond organ. The first models to be produced were the 20-watt A-20 and 40-watt A-40. The A-20 was designed for churches and small-capacity halls, and featured a set of doors in front of the speaker, that could be closed when the organ was not in use. The D-20 was introduced in 1937 and only allowed sound from the speakers to escape by a louvered opening on one side and a gap in the top. The most commercially successful set of Tone Cabinets were probably the PR series cabinets introduced in 1959. The 40-watt PR40 weighed and was high. It has a good response from bass pedals.


Leslie speaker

Many players prefer to play the Hammond through a cabinet with a rotating speaker known, after several name changes, as a
Leslie speaker The Leslie speaker is a combined amplifier and loudspeaker that projects the signal from an electric or electronic instrument and modifies the sound by rotating a baffle chamber ("drum") in front of the loudspeakers. A similar effect is provided ...

Doppler effect The Doppler effect (also Doppler shift) is the change in the frequency of a wave in relation to an observer who is moving relative to the source of the wave. The ''Doppler effect'' is named after the physicist Christian Doppler, who described ...
created by the moving sound sources. The Leslie was originally designed to mimic the complex tones and constantly shifting sources of sound emanating from a large group of ranks in a pipe organ. The effect varies depending on the speed of the rotors, which can be toggled between fast (tremolo) and slow (chorale) using a console half-moon or pedal switch, with the most distinctive effect occurring as the speaker rotation speed changes. The most popular Leslies were the 122, which accepted a balanced signal suitable for console organs, and the 147, which accepted an unbalanced signal and could be used for spinet organs with a suitable adapter. The Pro-Line series of Leslies which were made to be portable for gigging bands using solid-state amps were popular during the 1970s. Leslie initially tried to sell his invention to Hammond, but Laurens Hammond was unimpressed and declined to purchase it. Hammond modified their interface connectors to be "Leslie-proof", but Leslie quickly engineered a workaround. Some Hammond staff thought Laurens Hammond was being irrational and autocratic towards Leslie, but Don Leslie later said it helped give his speakers publicity. The Leslie company was sold to

in 1965, and the following year, Hammond finally decided to officially support the Leslie speaker. The T-200 spinet, introduced in 1968, was the first Hammond to have an integrated Leslie speaker. Hammond finally purchased Leslie in 1980. Hammond-Suzuki acquired the rights to Leslie in 1992; the company currently markets a variety of speakers under this name. As well as faithful reissues of the original 122 speaker, the company announced in 2013 that they would start manufacturing a standalone Leslie simulator in a stomp box.

system, which is driven by a metal scanner. As the scanner rotates around a set of pickups, it changes the pitch of the overall sound slightly. From here, the sound is sent to the main amplifier, and on to the audio speakers. The Hammond organ makes technical compromises in the notes it generates. Rather than produce harmonics that are exact multiples of the fundamental as in

. However, the sound of tonewheel crosstalk is now considered part of the signature of the Hammond organ, to the extent that modern digital clones explicitly emulate it. Some Hammond organs have an audible pop or click when a key is pressed. Originally, key click was considered a design defect and Hammond worked to eliminate or at least reduce it with equalization filters. However, many performers liked the percussive effect, and it has been accepted as part of the classic sound. Hammond research and development engineer Alan Young said, "the professionals who were playing popular music ikedthat the attack was so prominent. And they objected when it was eliminated." Because the tones on a Hammond organ are mechanically generated, different models were manufactured for the US and European markets, which run on 110 V/60 Hz and 240 V/50 Hz

Clones and emulation devices

The original Hammond organ was never designed to be transported regularly. A Hammond B-3 organ, bench, and pedalboard weighs . This weight, combined with that of a Leslie speaker, makes the instrument cumbersome and difficult to move between venues. This created a demand for a more portable and reliable way of generating the same sound. Electronic and digital keyboards that imitate the sound of the Hammond are referred to as "

''Sound on Sound'' Gordon Reid said that the CX-3 "came close to emulating the true depth and passion of a vintage Hammond", particularly when played through a Leslie speaker. The Roland VK-7, introduced in 1997, attempted to emulate the sound of a Hammond using
