The Mellotron is an electro-mechanical musical instrument developed in Birmingham, England, in 1963. It is played by pressing its keys, each of which causes a length of magnetic tape to contact a capstan, which pulls it across a playback head. As the key is released, the tape is retracted by a spring to its initial position. Different portions of the tape can be played for different sounds.

The Mellotron evolved from the similar Chamberlin, but could be mass-produced more efficiently. The first models were designed for the home and contained a variety of sounds, including automatic accompaniments. Bandleader Eric Robinson and television personality David Nixon helped promote the first instruments, and celebrities such as Princess Margaret were early adopters. It was adopted by rock and pop groups in the mid to late 1960s. One of the first pop songs featuring the Mellotron was Manfred Mann's "Semi-Detached, Suburban Mr. James" (1966). The Beatles used it on tracks including the hit single "Strawberry Fields Forever" (1967).

The Moody Blues keyboardist Mike Pinder used it extensively on the band's 1967 album Days of Future Passed as well as the group's following six albums. During the 1970s, the Mellotron became common in progressive rock, used by groups such as King Crimson, Yes, and Genesis. Later models, such as the bestselling M400, dispensed with the accompaniments and some sound selection controls so it could be used by touring musicians. The instrument's popularity declined in the 1980s after the introduction of polyphonic synthesizers and samplers, despite high-profile performers such as Orchestral Manoeuvres in the Dark and XTC continuing to use the instrument.

Production of the Mellotron ceased in 1986, but it regained popularity in the 1990s and was used by bands such as Oasis, the Smashing Pumpkins, Muse, and Radiohead. This led to the resurrection of the original manufacturer, Streetly Electronics. In 2007, Streetly produced the M4000, which combined the layout of the M400 with the bank selection of earlier models.

Operation

File:Mellotron diagram.svg

The internal operations of a Mellotron. Pressing a key (1), causes two screws (2) to connect a pressure pad (3) with the tape head (5), and the pinch wheel (4) with the continuously rotating capstan (6). Tape is pulled at a constant speed, counterbalanced by a tension spring (8–10) and stored temporarily in a storage bin (7) until the key is released.

The Mellotron uses the same concept as a sampler, but generates its sound using analogue recordings on audio tape. When a key is pressed, a tape connected to it is pushed against a playback head, as in a tape deck. While the key remains depressed, the tape is drawn over the head, and a sound is played. When the key is released, a spring pulls the tape back to its original position.

A variety of sounds are available on the instrument. On earlier models, the instrument is split into "lead" and "rhythm" sections. There is a choice of six "stations" of rhythm sounds, each containing three rhythm tracks and three fill tracks. The fill tracks can also be mixed together.Template:Rp Similarly, there is a choice of six lead stations, each containing three lead instruments which can be mixed. In the centre of the Mellotron, there is a tuning button that allows a variation in pitch (tempo, in the case of the rhythm tracks).Template:Rp Later models do not have the concept of stations and have a single knob to select a sound, along with the tuning control. However, the frame containing the tapes is designed to be removed, and replaced with one with different sounds.

Although the Mellotron was designed to reproduce the sound of the original instrument, replaying a tape creates minor fluctuations in pitch (wow and flutter) and amplitude, so a note sounds slightly different each time it is played. Pressing a key harder allows the head to come into contact under greater pressure, to the extent that the Mellotron responds to aftertouch.

Another factor in the Mellotron's sound is that the individual notes were recorded in isolation. For a musician accustomed to playing in an orchestral setting, this was unusual, and meant that they had nothing against which to intonate. Noted cellist Reginald Kilbey refused to downtune his cello to cover the lower range of the Mellotron, and so the bottom notes are actually performed on a double bass. According to Mellotron author Nick Awde, one note of the string sounds contains the sound of a chair being scraped in the background.

When the Chamberlin was first developed, the initial recorded sound used was that of three violins, thereby committing the instrument range to G3 to F6, being the range of the violin. Unfortunately, as with the cello, many other instruments did not conform to this range. The noted solo flute (which appears on the introduction to Strawberry Fields Forever) actually comprises recordings from an alto flute and a soprano flute, which accounts for some of the odd tuning that appears when chords are played. Other sounds such as the brass opted for a layered effect where instruments were recorded within their correct range. Others recorded more recently, such as the bass clarinet opt instead to drop the tuning on the lowest notes by pitching them electronically. The Mellotron choir was recorded in two halves: four men in one studio, and four women in another adjacent, thereby allowing for the actual recording of three sounds concurrently. In this, the male singers from the Ted Taylor Choir were allowed to drop the highest notes back to the previous octave as they were considerably out of their natural range.

The original Mellotrons were intended to be used in the home or in clubs and were not designed for touring bands. Even the later M400, which was designed to be as portable as possible, weighed over 122 pounds (55 kg). Smoke, variations in temperature, and humidity were also detrimental to the instrument's reliability. Moving the instrument between cold storage rooms and brightly lit stages could cause the tapes to stretch and stick on the capstan. Leslie Bradley recalls receiving some Mellotrons in for a repair "looking like a blacksmith had shaped horseshoes on top". Pressing too many keys at once caused the motor to drag, resulting in the notes sounding flat. Robert Fripp stated that "[t]uning a Mellotron doesn't". Dave Kean, an expert Mellotron repairer, recommends that older Mellotrons should not be immediately used after a period of inactivity, as the tape heads can become magnetised in storage and destroy the recordings on them if played.

History

Although tape samplers had been explored in research studios, the first commercially available keyboard-driven tape instruments were built and sold by California-based Harry Chamberlin. The concept of the Mellotron originated when Chamberlin's sales agent, Bill Fransen, brought two of Chamberlin's Musicmaster 600 instruments to England in 1962 to search for someone who could manufacture 70 matching tape heads for future Chamberlins. He met Frank, Norman, and Les Bradley of tape engineering company Bradmatic Ltd, who said they could improve on the original design. The Bradleys subsequently met bandleader Eric Robinson, who agreed to help finance the recording of the necessary instruments and sounds. Together with the Bradleys and television celebrity David Nixon (Robinson's son-in-law), they formed a company, Mellotronics, in order to market the instrument. Robinson was particularly enthusiastic about the Mellotron because he felt it would revitalise his career, which was then on the wane. He arranged the recording sessions at IBC Studios in London, which he co-owned with George Clouston.

The first model to be commercially manufactured was the Mk I in 1963. An updated version, the Mk II, was released the following year and featured the full set of sounds selectable by banks and stations. The instrument was expensive, costing £1,000 (equivalent to £18,265 in 2025), at a time when a typical house cost £2,000–£3,000.

Fransen failed to explain to the Bradleys that he was not the owner of the concept, and Chamberlin was unhappy with the fact that someone overseas was copying his idea. After some acrimony between the two parties, a deal was struck between them in 1966, whereby they would both continue to manufacture instruments independently. Bradmatic renamed themselves Streetly Electronics in 1970.

In 1970, the model M400 was released, which contained 35 notes (G–F) and a removable tape frame. It sold over 1,800 units. In the early 1970s, hundreds of the instruments were assembled and sold by EMI under exclusive licence. Following a financial and trademark dispute through a US distribution agreement, the Mellotron name was acquired by American-based Sound Sales. Streetly-manufactured instruments after 1976 were sold under the name Novatron. The American Mellotron distributor, Sound Sales, produced their own Mellotron model, the 4-Track, in the early 1980s. At the same time Streetly Electronics produced a road-cased version of the 400 – the T550 Novatron. By the mid-1980s, both Sound Sales and Streetly Electronics suffered severe financial setbacks, losing their market to synthesizers and solid-state electronic samplers, which rendered the Mellotron essentially obsolete. The company folded in 1986, and Les Bradley threw most of the manufacturing equipment into a skip. From 1963 until Streetly's closure, around 2,500 units had been built.

Streetly Electronics was subsequently reactivated by Les Bradley's son John and Martin Smith. After Les Bradley's death in 1997, they decided to resume full-time operation as a support and refurbishment business. By 2007, the stock of available instruments to repair and restore was diminishing, so they decided to build a new model, which became the M4000. The instrument combined the features of several previous models, and featured the layout and chassis of an M400 but with a digital bank selector that emulated the mechanical original in the Mk II.

Notable users

The first notable musician to use the Mellotron was variety pianist Geoff Unwin, who was specifically hired by Robinson in 1962 to promote the use of the instrument. He toured with a Mk II Mellotron and made numerous appearances on television and radio. Unwin claimed that the automatic backing tracks on the Mk II's left-hand keyboard allowed him to provide more accomplished performances than his own basic skills on the piano could provide.

The earlier 1960s Mk II units were made for the home and the characteristics of the instrument attracted a number of celebrities. Among the early Mellotron owners were Princess Margaret, Peter Sellers, King Hussein of Jordan and Scientology founder L. Ron Hubbard (whose Mellotron was installed in the Church of Scientology's head UK office at Saint Hill Manor). According to Robin Douglas-Home, Princess Margaret "adored it; (Lord Snowdon) positively loathed it".

After Mellotronics had targeted them as a potential customer, the BBC became interested in the possibilities of the instrument, hoping it would allow them to increase throughput at the Radiophonic Workshop. Two custom-made models loaded with sound effects were acquired in 1963, but the Radiophonic Workshop were unenthusiastic and problems with fluctuating tape speed and noise meant the sound was not up to professional broadcast quality. They ended up in the BBC FX library.

British multi-instrumentalist Graham Bond is considered the first rock musician to record with a Mellotron, beginning in 1965. The first hit song to feature a Mellotron Mk II was "Baby Can It Be True", which Bond performed live with the machine in televised performances, using solenoids to trigger the tapes from his Hammond organ. Manfred Mann then included multiple Mellotron parts on their single, "Ha! Ha! Said the Clown".

Template:Reduced pull quote Mike Pinder worked at Streetly Electronics for 18 months in the early 1960s as a tester, and was immediately excited by the possibilities of the instrument. After trying piano and Hammond organ, he settled on the Mellotron as the instrument of choice for his band, the Moody Blues, purchasing a second-hand model from Fort Dunlop Working Men's Club in Birmingham and using it extensively on every album from Days of Future Passed (1967) to Octave (1978).

Pinder says he introduced John Lennon and Paul McCartney to the Mellotron, and persuaded each of them to buy one. The Beatles hired a machine and used it on their single "Strawberry Fields Forever", recorded in various takes between November and December 1966. Author Mark Cunningham describes the part in "Strawberry Fields Forever" as "probably the most famous Mellotron figure of all-time". Although producer George Martin was unconvinced by the instrument, describing it "as if a Neanderthal piano had impregnated a primitive electronic keyboard", they continued to compose and record with various Mellotrons for the albums Magical Mystery Tour (1967) and The Beatles (1968, also known as "the White Album"). McCartney went on to use the Mellotron sporadically in his solo career.

The instrument became increasingly popular among rock and pop bands during the psychedelic era, adding what author Thom Holmes terms "an eerie, unearthly sound" to their recordings. Brian Jones of the Rolling Stones played a Mellotron on several of his band's songs over 1967–68. These include "We Love You", where he used the instrument to create a Moroccan-sounding horn section, "She's a Rainbow", "2000 Light Years from Home" and "Jigsaw Puzzle".

File:Robert Fripp 2.jpg

Robert Fripp played the Mellotron on several King Crimson albums, and said that "Tuning a Mellotron doesn't [tune it]"

The Mellotron became a key instrument in progressive rock. King Crimson bought two Mellotrons when forming in 1969. They were aware of Pinder's contributions to the Moody Blues and did not want to sound similar, but concluded there was no other way of generating the orchestral sound. The instrument was originally played by Ian McDonald, and subsequently by Robert Fripp upon McDonald's departure. Later member David Cross recalled he did not particularly want to play the Mellotron, but felt that it was simply what he needed to do as a member of the band.

Tony Banks bought a Mellotron from Fripp in 1971, which he claimed was previously used by King Crimson, to use with Genesis. He decided to not use the instrument as though it were an orchestra, instead using block chords. He went on to explain that he used it in the same manner as a synth pad on later albums. His unaccompanied introduction to "Watcher of the Skies" on the album Foxtrot (1972), played on a Mk II with combined strings and brass, became significant enough that Streetly Electronics provided a "Watcher Mix" sound with the M4000. Banks claims to still have a Mellotron in storage, but does not feel inclined to use it as he generally prefers to use up-to-date technology. Barclay James Harvest's Woolly Wolstenholme bought an M300 primarily to use for string sounds, and continued to play an M400 live into the 2000s as part of a reformed band.

Rick Wakeman played Mellotron on David Bowie's 1969 hit song "Space Oddity". Having previously found it difficult to keep in tune, Wakeman had discovered a way to do so using a special fingering technique.

The Mellotron was used extensively by German electronic band Tangerine Dream through the 1970s, on albums such as Atem (1973), Phaedra (1974), Rubycon (1975), Stratosfear (1976), and Encore (1977). In the late 1970s, French duo Space Art used a Mellotron during the recording of their second album, Trip in the Centre Head. In 1983, the band's Christopher Franke asked Mellotronics if they could produce a digital model, as the group migrated towards using samplers.

Although the Mellotron was not extensively used in the 1980s, a number of bands featured it as a prominent instrument. One of the few UK post-punk bands to do so was Orchestral Manoeuvres in the Dark, who featured it heavily on their platinum-selling 1981 album Architecture & Morality. Andy McCluskey has stated they used the Mellotron because they were starting to run into the limitations of the cheap monophonic synthesizers they had used up to that point. He bought a second-hand M400 and was immediately impressed with the strings and choir sounds. XTC's Dave Gregory recalls seeing bands using Mellotrons when growing up in the 1970s, and thought it would be an interesting addition to the group's sound. He bought a second-hand model in 1982 for £165, and first used it on the album Mummer (1983). IQ's Martin Orford bought a second-hand M400 and used it primarily for visual appeal rather than musical quality or convenience.

The Mellotron resurfaced in 1995 on Oasis' album (What's the Story) Morning Glory? The instrument was played by both Noel Gallagher and Paul Arthurs on several tracks, but a particularly prominent use was the cello sound on the hit single "Wonderwall", played by Arthurs. It also notably appears on their 2000 single "Go Let It Out". Radiohead asked Streetly Electronics to restore and repair a model for them in 1997, and recorded with it on several tracks for their album OK Computer (1997). The French electronic duo Air extensively used a M400 on their two first albums Moon Safari in 1998 and The Virgin Suicides in 1999.

Spock's Beard's Ryo Okumoto is a fan of the Mellotron, saying it characterises the sound of the band. Porcupine Tree's Steven Wilson has acquired one of King Crimson's old Mellotrons and, in 2013, gave a demonstration of the instrument in celebration of its 50th anniversary.

Competitors

Alternatives to the Mellotron were manufactured by competitors in the early to late 1970s. The Mattel Optigan was a toy keyboard designed to be used in the home, which played back sounds using optical discs. This was followed by the Vako Orchestron in 1975, which used a more professional-sounding version of the same technology. It was used by Patrick Moraz. The Birotron was a similar concept based around 8-track cartridges, used by Wakeman.
