EWI

From Wikipedia, the free encyclopedia

An EWI

The EWI (an acronym for Electronic Wind Instrument) is an electronic musical instrument developed by the Akai Electronic Musical Instruments Corporation of Japan. The early models consisted of two parts: a wind controller and a synthesizer. The current model, EWI 4000S, combines the two parts into one, placing the synthesizer in the lower section of the controller. It uses the Boehm fingering system and is designed to be similar in action to a soprano saxophone. Like a soprano sax, it is straight, and is held in front of the body with a neck strap. The major manufacturers of wind controllers are Akai and Yamaha. Available models include the AKAI-EWI3020, AKAI-EWI4000s, Yamaha WX-5, Yamaha WX-11, and Yamaha WX-7. There is also a controller intended to be played by brass instrumentalists called an EVI (for Electric Valve Instrument). The Akai EWI4000S has a special EVI mode that allows brass players to play the EWI. There are also homemade and experimental EWIs with different designs.

The wind controller part of the EWI has a mouthpiece with sensors for air pressure (volume control) and lip pressure (vibrato). The EWI keys do not move, but work through conductivity, sensing the positioning of the fingers by electrical current; this allows for very fast playing. The octave is determined by a set of rollers operated by the left thumb. The wind controller is used to control a synthesizer. Some EWIs have to be attached to a specific synth module, and some have direct output to the MIDI interface.

Though it is usually associated with jazz/rock fusion and, more recently, with New Age music, the EWI is a musically versatile instrument. The air pressure sensor allows for great dynamic range, especially in combination with an analog synthesizer. Tonal range is also great, usually extending to 8 octaves.

[edit] Performers

Skilled EWI players include Bob Mintzer and Michael Brecker. Brecker in particular has played the EWI both as a solo instrumentalist and in an ensemble context with groups like Steps Ahead and Paul Simon's band. Steve Tavaglione is another famous EWI player who plays on jazz albums but is best known for his TV and film soundtrack work. His EWI playing can be heard on TV shows like CSI: NY and movies including Finding Nemo, Ocean's 11 and Ocean's 12.

Since the late 1980s the EWI has been well known to fans of the Japanese Fusion (J-Fusion) band T-SQUARE as a lead instrument. All three of the band's saxophonists double on EWI. T-SQUARE has included 2 or 3 new compositions for EWI on each of their albums.
