The Yamaha CP-70 is an electric piano manufactured by Yamaha Corporation between 1976 and 1985. The instrument was based on earlier electric piano technology, but took advantage of improved pickups along with the company's longstanding experience in manufacturing acoustic pianos.

Contents

The new technology and a lack of a soundboard gave it a more accurate emulation of an acoustic piano than earlier models. It was well received and used by a number of musicians in the late 1970s and early 1980s, including the Grateful Dead's Keith Godchaux and Genesis' Tony Banks. It continues to be used in the 21st century by a number of artists, and it is still possible to buy replacement parts.

Features

Internal view of the piano

The CP-70 has the same key action as an acoustic piano, but does not contain a soundboard. It has a smaller number of specially manufactured strings, reducing the overall weight. [1] In particular, the bass strings are very short compared to an acoustic instrument (2+13 inches (5.9 cm) instead of around 9 feet (3 m)). [2] The strings are amplified by piezo-electric pickups mounted on the harp casting that induce an electric current from vibrations, in a similar manner to pickups on an acoustic guitar. [3]

The choice of piezo-electric pickups and their mounting position avoids the problems with earlier electric pianos, where magnetic pickups carried harmonic information at a particular distance on the string. The lack of a soundboard means it is difficult for the instrument to feedback. [3] The signal from the pickups is sent to a preamplifier which features a stereo balanced line signal via a pair of XLR connector output jacks, in addition to the more familiar quarter-inch jack outputs. [4]

The CP-70 is designed for touring. The instrument's legs are detachable and can be stored in an internal lid. The harp can be detached from the key assembly, though this requires two people. [5] An optional road case is available. [4] The CP-70's flat top allows other keyboards and synthesisers to be stacked on top of it. [5]

Background

There had been numerous attempts to manufacturer a piano that was both portable and sounded like the acoustic grand model. Benjamin Miessner had been working on pickup and amplification techniques since the 1930s, and discovered that capturing the harmonic information and nuances of sound was difficult and changed as pickup positions and configurations were altered. [6] Yamaha had been working on pickup technology since World War II, and took advantage of Japanese culture at the time which permitted research information to be exchanged between companies without threat of intellectual property lawsuits, as in the US. [3] They used this knowledge to create a series of robust piezo-electric pickups, and combined it with their experience in manufacturing acoustic pianos to make an electric instrument. [3]

The CP-70 was first manufactured in 1976, and cost $4,000. [4] According to Toto's David Paich, Yamaha invited a group of pianists in Los Angeles to test the instrument before manufacturing. After playing, they were "just freaking out over it". [2] The first model had problems with tuning, and an upgraded version, the CP-70B, was introduced at the NAMM Show in 1978, along with the CP-80, which featured a full 88-note keyboard. [5] The CP-70D and CP-80D models featured a graphic equaliser and an effects loop. The final models to be released were the MIDI equipped CP-70M and CP-80M, which were released at the end of 1985. [4]

Maintenance

The CP-70B and later models have very stable tuning, compared to other electric pianos. The lack of a soundboard means that vibration from transport and humidity is unlikely to change the sound. [7]

Because the CP-70 uses custom-made strings, sourcing new ones can be problematic. Each iteration of the instrument used a different type of string, although some of the treble strings can be replaced with standard ones from an acoustic piano. As of 2019, there were two companies in the US supplying the appropriate custom strings for the CP-70. [8]

The CP-70 was used by a number of prominent keyboardists, including Keith Emerson, George Duke, Little Feat's Bill Payne, Heart's Howard Leese, Patrick Moraz, Michael McDonald, Magne Furuholmen of A-ha and Billy Joel. [9] During Cold Chisel's live performances, singer Jimmy Barnes leapt onto keyboardist Don Walker's CP-70. [10] The Grateful Dead's Keith Godchaux began playing a CP-70 as it was easier to transport one to gigs than an acoustic grand piano. [11] Led Zeppelin's John Paul Jones encased a CP-70 inside a white case to resemble an acoustic piano. [1] Genesis' Tony Banks used the instrument extensively, such as the hit "That's All" and "Taking It All Too Hard", and preferred recording with it over an acoustic piano. [5]

The CP-70 achieved its commercial peak during the advent of MTV and was therefore prominently featured on music videos. [5] Keane's Tim Rice-Oxley uses a CP-70 as his main instrument with the band. [1] Alicia Keys has used a CP-70 as her main touring piano, which she custom-painted. During the tour for The Element of Freedom , her CP-70 featured the words "Freedom" and "Love" painted on its side. [5]

The piano is a keyboard instrument that produces sound when the keys are pressed. Most modern pianos have a row of 88 black and white keys: 52 white keys for the notes of the C major scale and 36 shorter black keys raised above the white keys and set further back, for sharps and flats. This means that the piano can play 88 different pitches, spanning a range of a bit over seven octaves. The black keys are for the "accidentals", which are needed to play in all twelve keys.

<span class="mw-page-title-main">Rhodes piano</span> Electric piano

The Rhodes piano is an electric piano invented by Harold Rhodes, which became popular in the 1970s. Like a conventional piano, the Rhodes generates sound with keys and hammers, but instead of strings, the hammers strike thin metal tines, which vibrate next to an electromagnetic pickup. The signal is then sent through a cable to an external keyboard amplifier and speaker.

<span class="mw-page-title-main">Electric piano</span> Electro-mechanical keyboard musical instrument

An electric piano is a musical instrument that has a piano-style musical keyboard, where sound is produced by means of mechanical hammers striking metal strings or reeds or wire tines, which leads to vibrations which are then converted into electrical signals by pickups. The pickups are connected to an instrument amplifier and loudspeaker to reinforce the sound sufficiently for the performer and audience to hear. Unlike a synthesizer, the electric piano is not an electronic instrument. Instead, it is an electro-mechanical instrument. Some early electric pianos used lengths of wire to produce the tone, like a traditional piano. Smaller electric pianos used short slivers of steel to produce the tone. The earliest electric pianos were invented in the late 1920s; the 1929 Neo-Bechstein electric grand piano was among the first. Probably the earliest stringless model was Lloyd Loar's Vivi-Tone Clavier. A few other noteworthy producers of electric pianos include Baldwin Piano and Organ Company, and the Wurlitzer Company.

The Hohner Pianet is a type of electro-mechanical piano built by the Hohner company of Trossingen, West Germany and designed by Ernst Zacharias. The Pianet was a variant of his earlier reed-based Hohner electric piano, the Cembalet, which, like the Pianet, was intended for home use. Hohner offered both keyboards in their range until 1968. The Pianet production consisted of two distinctly different mechanism groups with characteristically different sound. The first group, lasting from introduction to 1977, had ground stainless steel reeds, a pick-up using variable capacitance, and leather-faced activation pads. The second group from 1977 until the end of production used rolled spring-steel reeds, electro-magnetic pick-ups, and moulded silicone rubber activation pads.

<span class="mw-page-title-main">Pickup (music technology)</span> Captures vibrations produced by musical instruments

A pickup is a transducer that captures or senses mechanical vibrations produced by musical instruments, particularly stringed instruments such as the electric guitar, and converts these to an electrical signal that is amplified using an instrument amplifier to produce musical sounds through a loudspeaker in a speaker enclosure. The signal from a pickup can also be recorded directly.

A stage piano is an electronic musical instrument designed for use in live performances on stage or in a studio, as well as for music recording in Jazz and popular music. While stage pianos share some of the same features as digital pianos designed for home use and synthesizers, they have a number of features which set them apart. Stage pianos usually provide a smaller number of sounds, with these being of higher quality than the ones found on regular digital pianos and home synthesizers.

The Wurlitzer electronic piano is an electric piano manufactured and marketed by Wurlitzer from 1954 to 1983. Sound is generated by striking a metal reed with a hammer, which induces an electric current in a pickup. It is conceptually similar to the Rhodes piano, though the sound is different.

<span class="mw-page-title-main">Electric grand piano</span>

The electric grand piano is a stringed musical instrument played using a keyboard, in which the vibration of strings struck by hammers is converted by pickups into electrical signals, analogous to the electric guitar's electrification of the traditional guitar.

An acoustic guitar is a musical instrument in the string family. When a string is plucked, its vibration is transmitted from the bridge, resonating throughout the top of the guitar. It is also transmitted to the side and back of the instrument, resonating through the air in the body, and producing sound from the sound hole. While the original, general term for this stringed instrument is guitar, the retronym 'acoustic guitar' – often used incorrectly to indicate the steel stringed model – distinguishes it from an electric guitar, which relies on electronic amplification. Typically, a guitar's body is a sound box, of which the top side serves as a sound board that enhances the vibration sounds of the strings. In standard tuning the guitar's six strings are tuned (low to high) E2 A2 D3 G3 B3 E4.

Classical electric guitars, also known as nylon-string electric guitars, represent a unique fusion of traditional classical guitar design and modern electric guitar technology. These instruments combine the rich and warm tonal qualities of nylon-stringed classical guitars with the versatility and amplified sound capabilities of electric guitars. By integrating nylon strings with onboard electronics, pickups, and preamp systems, classical electric guitars offer musicians a wide range of sonic possibilities for various musical genres and performance settings.

Yamaha CP88 and Yamaha CP73 are professional stage pianos produced by Yamaha. These instruments are identical except for keyboard action and size. The instruments are designed to be played at live concerts on the stage, and are also suitable for recording studios due to their versatility of sound. As they are intended for professional use in locations with a preinstalled sound system, such as concert venues and recording studios, they do not have internal speakers, like the home instruments.
