The keytar is a relatively lightweight synthesizer that is supported by a strap around the neck and shoulders, similar to the way a guitar is supported by a strap. Keytars allow players a greater range of movement onstage, compared to conventional keyboards, which are placed on stationary stands or which are part of heavy, floor-mounted structures. The instrument has a musical keyboard for triggering musical notes and sounds. Various controls are placed on the instrument's "neck", including those for pitch bends, vibrato, portamento, and sustain.
The term "keytar" is a portmanteau of the words "keyboard" and "guitar", and is a slang word. This style of keyboard was mostly referred to by manufacturers as a "MIDI Controller", "Remote Keyboard", "Strap-on Keyboard", or variations thereof. Though the term "keytar" has been used since the introduction of the instrument, it was not used by a major manufacturer until 2012, when the Alesis company referred to the "Vortex", the company's first product of this type, as a "USB/MIDI Keytar Controller". CEO and co-founder of Tap Tap Strum, Kyle Zimmerman, later came out with the design for the Keytar L8R. The Roland AX-Edge, which incorporates its own synthesis engine, is referred to by the manufacturer as a "keytar".
Keytars may either contain their own synthesizer engines, or be MIDI controllers. In either case, a keytar needs to be connected to a keyboard amplifier or PA system to produce a sound that the performer and audience can hear. MIDI controller keytars trigger notes and other MIDI data on an external MIDI-capable synthesizer, sound module or computer with synthesizer software. While keytars are usually used to create musical sounds, like any other MIDI controller, it could also be used to trigger such as MIDI-enabled lighting controllers, effects devices and audio consoles.
The oldest forerunner of the keytar probably is the orphica, a small portable piano invented in Vienna in 1795, which was played in a similar position as the modern keytar. The piano accordion first appeared in 1852. In 1963, the East German manufacturer Weltmeister introduced the Basset, as an electric bass piano in keytar shape.
In 1966, Swedish organ manufacturer Joh Mustad AB introduced the Tubon, an electric organ in the shape of a tube. This instrument was worn with a strap around the shoulder and could be played standing or sitting. The Tubon had a half-keyboard on one end accessible to the right hand, controls to be used at the "neck" on the opposite end for the left hand, and a speaker at the end of the tube. It was sold in the UK as the Livingstone. It saw use by Kraftwerk and Paul McCartney in the 1960s and early 1970s.
In the early 1970s, Edgar Winter often performed with keyboards slung around his neck, but they were not technically keytars because they had no "neck"; he actually used an ARP 2600 keyboard and a lightweight Univox electronic piano with shoulder straps added.
In late 1970s and early 1980s, Jan Hammer, the composer best known for his composition and sound design successes for Miami Vice, frequently used several keytars including Royalex PROBE which he helped develop. Jan is seen for instance using his PROBE in the music video for the "Miami Vice Theme". Also in the 1980s, Wayne Famous of the band the Producers strapped on a regular Oberheim synthesizer, which caused him to develop back problems.
The earlier keytars commercially released in late 1970s–early 1980s includes:
etc. (for details, see List of keytars)
Among them, the most widely known earlier keytar may be the "Moog Liberation" released in 1980. Early users included Spyro Gyra keyboardist Tom Schuman. Though Devo is associated with keytars, they never used them except in music videos and promotional ads for the Liberation. The earliest printed use of the word "keytar" was in 1980, when it appeared in an interview with Jeffrey Abbott (Keytarjeff) by Tom Lounges of Illianabeat magazine (now Midwest BEAT Magazine) who now hosts a weekly interview show featuring legends of the music industry on N.W. Indiana's PBR radio station.
Although Steve Masakowski has been incorrectly credited for many years as the inventor of the keytar, in an interview with Peter Hartlaub of the San Francisco Chronicle on December 11, 2009, he only claimed to have invented an instrument called the Key-tar which was a string-based instrument.
The keytar was made popular in the 1980s by glam metal bands, as well as synthpop, new wave and electro musicians. Changing trends in music diminished the keytar's popularity during the 1990s, continuing on until the late 2000s when a major revival was sparked by artists and groups such as The Black Eyed Peas, Flight of The Conchords, Motion City Soundtrack, No Doubt, and Steely Dan. Another instance is in early 2008 with Snoop Dogg's music video for his single "Sensual Seduction", in which he uses a keytar as a throwback to old school bands.
Notable manufacturers of keytar models have included Moog, Roland, Yamaha, Korg and Casio. As of 2013, the Roland AX-Synth, the Roland Lucina, the Alesis Vortex and Rock Band 3 Wireless Pro Keyboard, are the mass-manufactured keytars on the market.
The Moog Liberation was released in 1980 by Moog Music, and was considered the first mass-produced strap synthesizer. It included two monophonic VCOs and a polyphonic section that could play organ sounds. The neck had spring-loaded wheels for filter cutoff, modulation, and volume as well as a ribbon-controlled pitch bend. The Liberation had a single VCF and two ADS envelope generators.
The Roland SH-101 is a small, 32-key, monophonic analog synthesizer from the early 1980s. It has one oscillator with two waveforms, an 'octave-divided' sub-oscillator, and a low-pass filter/VCF capable of self oscillation. When a shoulder strap is connected to it, and the small handgrip with a pitch bend wheel and a pitch modulation trigger is used, the SH-101 becomes a keytar.
The Yamaha SHS-10 from the late 1980s has a small keyboard with 32 minikeys and a pitch-bend wheel, an internal Frequency modulation (usually referred to as FM) synthesizer offering 25 different voices with 6-note polyphony. Onboard voices include a range of keyboard instruments (pipe organ, piano, electric piano, etc.); strings (violin, guitar, double bass, etc.); and wind and brass (clarinet, flute, trumpet, etc.).
The Roland AX-7, which was manufactured from 2001 to 2007, contains many more advanced features than early keytars. It has 45 velocity sensitive keys (without aftertouch), and a 3-character LED display. Several features aimed towards stage performance are present, such as a pitch bend ribbon, touchpad-like expression bar, sustain switch, and volume control knob, all on the upper neck of the instrument. There is also a proprietary "D-Beam" interface, made up of infrared sensors that detect nearby motion. This interface can be used to trigger and control effects.
In August 2009, Roland released the Roland AX-Synth, a model of keytar that contains its own synthesizer sounds in addition to being a MIDI/USB controller. In 2010, Roland released the Roland Lucina AX-09. This model does not have a traditional neck, but is still considered a keytar because of it is a strap-on model and is in the AX line, with many identical features to its AX predecessors. It is unique in that it includes an additional, front panel USB port to accommodate a USB flash drive, which may contain MP3, WAV or AIFF files for playback. The Lucina has 150 internal sounds and may also be used as a MIDI/USB controller.
Also in 2010, Mad Catz released the Wireless Pro Keyboard for Rock Band 3, a 25-key velocity-sensitive MIDI-compatible keytar controller. Despite its sub-$100 price, it is designed for serious use outside of the game. Synthpop band Freezepop have used it on stage.
In 2012, Alesis released its first ever keytar and is the first major manufacturer to actually use the term "keytar" in the model name and description. The Alesis Vortex USB/MIDI Keytar Controller is unique in that it includes eight velocity-sensitive drum pads/sample triggers, which enable the performer to create beats or trigger clips, built right into the body of the keytar. It also features a unique "accelerometer", which allows the performer to control MIDI parameters by tilting the neck. Although Alesis claims to have manufactured "the first USB keytar controller", the Roland AX-Synth and the Roland Lucina feature USB connections with the same function and were released three years prior to the Alesis Vortex.
