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

thumb|left|upright=1.3|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. 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). 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. 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. 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".

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".

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.

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.
