The University of Iowa Electronic Music Studios were founded in 1963, when renowned physicist James Van Allen (known for the Van Allen radiation belt) supervised a thesis project by James Cessna to build the world's first digital synthesizer. Van Allen persuaded the School of Music Composition Area to establish an electronic music studio, with Cessna as Research Assistant. Professor Robert Shallenberg was hired to direct the studios and work with Cessna on the synthesizer. Originally housed in a quonset hut with no air conditioning, Shallenberg and Cessna built their own speakers from kits, modified electronic-generating and recording equipment borrowed from the Physics Department, and worked on the digital synthesizer. Eventually, the digital synthesizer was replaced by a large Moog III synthesizer, which remains in operation today. During the mid-60s, many composers from other institutions visited the studios, among them Milton Babbitt, Edward Miller, John Melby, Josef Patowski (Warsaw Radio), Mel Powell, and others. One of the first student pieces completed was Paul Martin Zonn's Divertimento # 2 for clarinet and electronic tape. Other students during this period included Ball State University Professor Cleve Scott, Oberlin Professor Edwin Harkins, and electric string instrument designer Eric Jensen. In 1969, Shallenberg left for Indiana University, where he established an electronic music studio with Iannis Xenakis. Shallenberg later joined the faculty of University of California at San Diego. James Cessna went on to design the original time-of-flight circuitry for the Energetic Particles Detector composition telescope for the Galileo Spacecraft, launched in 1989.
Peter Tod Lewis joined the studios as director in 1969, assisted for many years by Peter Elsea (now Director of the Electronic Music Studios at the University of California, Santa Cruz) and Thomas Mintner (now with Audio Precision). In 1970, the studios moved to their new location in Voxman Music Building in rooms 2062, 2059, and 2058. A 1972 Rockefeller Foundation grant enabled Lewis to outfit the Studios with sophisticated analog synthesis, processing, and recording technology of the day, which he describes in a 1976 issue of the European journal Interface (now Journal of New Music Research). Among the studios' innovations was a computer interface for the Arp Synthesizer, designed and implemented by engineering student Donald E. Hall. Works produced for tape and live electronics with performers, film, lights, and lasers began to receive international recognition and helped attract such guest composers as Vladimir Ussachevsky, David Tudor, and Luciano Berio. Upon returning to the newly-founded IRCAM, Berio gave a presentation on developments in The Studios. Visiting Faculty who taught in the Studios during this period included Robert Ashley, Hubert Howe, Pril Smiley, and Morton Subotnick. Students during this period included Ralph Jackson (now president of BMI), instrument designer and author Thomas Henry, Oberlin professor Lewis Nielson, Northwestern Professor Stephen Syverud, University of Illinois Professor Heinrich Taube, University of Wisconsin-Milwaukee Professor Jon Welstead, and NYU Professor Robert Rowe. In 1979, Lewis created a classic audio demonstration of the Moog Synthesizer, which can be heard here.
The wide-ranging interests of Pulitzer Prize winning composer Kenneth Gaburo, appointed director in 1982, stimulated a new period of growth and experimentation for the Studios, as described in a 1995 issue of Perspectives of New Music dedicated to the late composer. New approaches to speech, text, and image manipulation were facilitated by the new computer technology that Gaburo introduced to the Studios. This multimedia emphasis continued into the early 1990s, as Visiting Directors Robert Paredes and Elizabeth Hinkle-Turner oversaw the installation of computer and video systems. Visitors during this period included Russell F. Pinkston, Chris Mann, and Warren Burt. Students included composer Bill Wolford, Cris Ewing (Studio Assistant at the University of Washington CARTAH), President of the American Composers Forum, Philip Blackburn, and Tape Beatles members Ralph Johnson, Paul Neff, and John Heck.
Lawrence Fritts was appointed director in 1994, overseeing a major upgrade to realtime DSP systems. In 1996, he initiated the Iowa Musical Instrument Samples Project, a collection of note-for-note samples of musical instruments recorded in an anechoic chamber. In 2000, he organized a series of International Exchange Concerts with institutions in France and Italy; and in 2002 he hosted the 2002 National Conference of the Society for Electro-Acoustic Music in the United States (SEAMUS). Recent visiting composers have included James Dashow, Elainie Lillios, Andrew May, Denis Smalley, and Charles Dodge. Students working during this period included Columbia University doctoral student Alexandre Lunsqui, NYU doctoral student Albin Jones, John Ritz, Experimental Music Studio Assistant at the University of Illinois and Chris Brakel, Computer Music Studio Assistant at the Eastman School of Music.
