[Elektronmusikstudion] (Swed.: ‘electronic music studio’)

The Swedish national centre for electronic music and sound art, in Stockholm. It was preceded by a smaller studio run by the Worker’s Society of Education from 1960. EMS was established by Swedish Radio in 1964 under music director and composer Karl Birger Blomdahl (1916–68), who hired the composer and performer Knut Wiggen (b 1927) to take charge of creating the studios. In 1965 an old radio theatre studio called the klangverstan (‘sound workshop’) opened for composers. Construction of a new facility was begun, but after Blomdahl’s death EMS became independent, funded only in small part by Swedish Radio, and otherwise by Fylkingen (a society for experimental music and arts) and the Swedish Royal Academy of Music.

Wiggen envisioned EMS as both a place to produce electro-acoustic music and a research institution that would give the composer ‘the possibility of describing sounds in psychological terms’. The studio was equipped accordingly. The sound sculpture ...

Unique MIDI synthesizer controlled by a gamma-ray spectrometer designed and built by Jerry Chamkis (b Los Angeles, CA, 1942). He studied physics at the University of California, Santa Barbara, but disillusioned by the emphasis on military applications, he left and became chief engineer at a radio station in Houston, Texas. In 1975, he formed AERCO (Acme Electric Robot Company), where he initially produced peripheral devices and memory expansions for small computers and then moved on to computer-controlled hot wire cutting systems, broadcast equipment, and microphone preamplifiers. Since about 2000 he has concentrated on various art projects such as the Kosmophone.

The gamma-ray spectrometer used for the Kosmophone operates at 3–7 million electron volts, the energy coming primarily from very high-energy cosmic radiation. Although mostly stopped by the atmosphere, gamma rays produce secondary energy emissions that the Kosmophone detects, sending the information to a synthesizer MIDI control port. The radiation pulses are processed and digitized to 12 bits, 7 of which are sent as the MIDI pitch value and 4 as the MIDI velocity value. The first Kosmophone was built from standard nuclear instrumentation modules and custom circuit boards. The second version is a self-contained portable unit with an integral detector, a self-contained nuclear analyser, an Alesis QSR synthesizer, and a 100-watt-per-channel amplifier. It was first shown publicly at the Electricity and Me show at Gallery Lombardi in Austin, Texas, in ...

(b Bermuda, July 10, 1957). American audio engineer, musician, and owner of Keith McMillen Instruments, based in Berkeley, California. He received his BS in acoustics from the University of Illinois, where he also studied classical guitar and composition. In 1979 he founded Zeta Music, which designed and sold electric and electronic violins and basses. In 1992 he organized a research laboratory for Gibson Guitars. He developed a computerized composition, notation, and performance system, and also helped devise ZIPI, a MIDI-like music control language. At the Center for New Music and Audio Technologies at the University of California, Berkeley, he researched audio networking, synthesizers, and string instruments. In 1996 he became director of engineering for the audio processing and distributed music networks division of Harmon Kardon. In 1999 he founded Octiv, Inc., an Internet audio signal processing company, which produced the ‘Volume Logic’ plug-in for iTunes that allows digital audio remastering to improve the sound produced by computers and MP3 players....

Portable electronic communication device. These have become robust platforms for digital audio production, composition, and music performance since the beginning of the 21st century. Recent compositions for mobile-phone ringtones might represent an emerging music genre. Since 2008, many commercial apps have transformed mobile devices into miniature synthesizers. Popular virtual-instrument programs such as Ocarina (2008) by the Smule Corporation and Band (2008) by MooCowMusic harness the phone’s numerous interfaces in various ways. Multi-point touch screens offer players the ability to manipulate graphical fingerholes, fretboards, drum pads, and keyboards, thus approximating the playing experience of acoustic wind, string, percussion, and keyboard instruments. Beyond its use in voice recording and transmission, a device’s microphone can register breath intensity, enabling users to initiate tones and alter dynamics as though playing a wind instrument.

Some mobile sound-production programs feature real-time voice manipulation, including auto-tune or pitch correction. Additional levels of musical functionality can be mapped to a phone’s accelerometer (an internal speed and direction detector). When the device is swung, shaken, or tilted, the accelerometer can trigger alterations in timbre, vibrato, pitch, and other variables. More advanced uses have been proposed. For example, a phone’s camera, acting as a real-time motion sensor, could affect many aspects of sound synthesis and sequencing; and the GPS (global positioning system) indicator has the potential to take location markers from other phones across the planet and turn those data into sonic information....

Sound-effects device that utilizes the player’s mouth as a resonator, allowing the player to form an electric guitar’s or other electronic instrument’s sounds into words and phrases. Output from a phenolic diaphragm speaker is sent through surgical tubing to the player’s mouth, where the sound is modified and picked up by a microphone.

The guitarist Alvino Rey initiated the technology in 1939. In 1950 the Nashville steel guitarist Pete Drake used a small low-powered loudspeaker and funnel coupled to a hose, but it only could be used in the recording studio. The rock guitarist Joe Walsh recorded his hit song ‘Rocky Mountain Way’ with Drake’s system, spurring the need for an onstage version. Bud Ross, owner of Kustom Electronics, introduced a portable 30-watt driver, but the low-powered diaphragm could not hold up to stage use. Walsh then asked Bob Heil (b St Louis, MO, 5 Oct 1940) to build a high-powered version for live performance. The resulting Heil Talk Box was introduced in ...
