John Chowning was born in Salem, New Jersey, in 1934. Following military service he studied music at Wittenberg University where he concentrated on composition and received his degree in 1959. He then studied composition in Paris for three years with Nadia Boulanger. In 1966 he received the doctorate in composition from Stanford University, where he studied with Leland Smith. With the help of Max Mathews of Bell Telephone Laboratories and David Poole of Stanford, in 1964 he set up a computer music program using the computer system of Stanford's Artificial Intelligence Laboratory. This was the first implementation of an on-line computer music system ever. Beginning in 1964 he began the research leading to the first generalized sound localization algorithm implemented in a quad format in 1966. In 1967, John Chowning discovered the frequency modulation (FM) algorithm in which both the carrier frequency and the modulating frequency are within the audio band. This breakthrough in the synthesis of timbres allowed a very simple yet elegant way of creating and controlling time-varying spectra. Over the next six years he worked toward turning this discovery into a system of musical importance. In 1973, he and Stanford University began a relationship with Yamaha in Japan, which led to the most successful synthesizer technology in the history of electronic musical instruments, known as FM synthesis. John Chowning has received fellowship grants from the National Endowment for the Arts and was artist-in-residence with the Kunstlerprogramm des Deutschen Akademischen Austauschdiensts for the City of Berlin in 1974, and guest artist in IRCAM, Paris in 1978, in 1981, and in 1985. His compositions have been recorded on compact disc, WERGO 2012-50. In 1983 he was honored for his contributions to the field of computer music at the International Computer Music Conference in Rochester, New York. He was elected to the American Academy of Arts and Sciences in 1988. In 1992 he was given The Osgood Hooker Professorship of Fine Arts by the School of Humanities and Sciences at Stanford. The French Ministry of Culture awarded him the Diplôme d'Officier de l'Ordre des Arts et Lettres in 1995 and he was given the Doctorat Honoris Causa December 2002 by the Université de la Méditerranée. Chowning taught computer-sound synthesis and composition at Stanford University's Department of Music and was founder and director of the Center for Computer Research in Music and Acoustics (CCRMA), one of the leading centers for computer music and related research.

 

 

John W. Rick is Associate Professor and past Chair of Anthropological Sciences at Stanford University, Curator of Anthropological Collections, and past Director of Stanford's Archaeology Center. His teaching concentrates on South American archaeology, the beginnings of social complexity, hunter–gatherers, stone tools, and digital methodologies in archaeology. For the last 14 years he has directed fieldwork at Chavín de Huántar, a monumental UNESCO World Heritage site dating to the first and second millennia B.C. Cooperative mapping, excavation, and conservation work there is done under long–term agreements with the Peruvian government. His interests there concentrate on understanding how early religious cults strategized the beginnings of political authority in the Andes. A previous long–term project focused on early hunter–gatherer cave sites in the 14,000 ft altitude puna grasslands of Peru, but he has also done archaeological fieldwork throughout South America and the American Southwest; he is also currently co–directing a major fieldwork project on Preclassic sites near Lake Atitlan in the Guatemalan highlands. His publications include books and articles ranging across these subjects, as well as additional topics of interest.

Cobi van Tonder is a South African born composer, media artist and lecturer, currently pursuing a PhD Digital Arts and Humanities, Trinity College, Dublin, Ireland. Music, sound art and inter-media works revolve around sound perception, multi-channel computer-generated composition, networked sound, acoustic studies, tools and methods for the control of spatiality in sound. The recursive theme in works are how they create, challenge and reinvent conceptions of the audio-physical experience of spaces and objects whilst maintaining a sense of mystery and beauty.

Van Tonder has also produced commercially for cinema, television, radio, and mobile media before commencing academic studies at a later age. She completed a MFA Art Practice degree at Stanford, USA; a BHons in Music in History and Society (Musicology) at the University of the Witwatersrand, Johannesburg, South Africa, a Jazz Diploma majoring in Film music and Jazz Piano at the Technikon of Pretoria, South Africa. Her work has been performed and showed in New York, London, San Jose, San Francisco, Seoul, Stuttgart, Berlin, Ogaki, Toronto, South Africa and Antarctica.

He has been a long-term denizen of the Center for Computer Research in Music and Acoustics, Stanford University where he directs the center and teaches computer music courses. His doctorate in music composition was completed at Stanford in 1983 with prior degrees in music from the University of California at San Diego and Antioch College. Two year-long research periods were spent at IRCAM, and the Banff Center for the Arts developing methods for computer sound synthesis based on physical models of musical instrument mechanics. Current projects include the "SoundWIRE" experiments for musical collaboration and network evaluation using high-speed internets for high-quality sound. He has performed his music in Europe, the Americas and Asia, and composed soundtracks for documentary films. Two recent discs of his works are available from Centaur Records. In Spring 2001, a collaboration with artist Greg Niemeyer entitled Ping was exhibited at SF MOMA and online via the Walker Art Center. A second collaboration, Oxygen Flute, was created for the San Jose Museum of Art. A CD of music from both installations is also available. "Organum" is their present project, a completely synthetic animation being developed for digital planetariums and individual game play.

Tito La Rosa is a musician, sociologist and builder of musical instruments, investigating the music of ancient Peru. He makes original instruments replicating those from pre-Inca and Inca cultures, using ceramics, bones, stones, feathers, seeds, leaves, wood and cane. Through a constant search for a cultural dialogue between times and dreams, the musical proposal of Tito la Rosa reunites the ancestral with the contemporary, fusing ancient musical instruments with contemporary elements. The intent of his work is the search for balance and harmony with oneself and with nature.

 

 

José Luis Cruzado Coronel, photographer, videographer, ceramicist and educator, has worked with Stanford Archaeology at Chavín de Huántar, Perú since 2000. His photography has been shown in international exhibits, including the Global Heritage Fund's 2010 show Preservation by Design: Safeguarding the World's Cultural Heritage. With María Mendoza, he has developed projects to recover ancient techniques in ceramics, bone and shell carving, and foster new artisan work in Chavín.

 

 

Silvia Rodriguez Kembel received her PhD from Stanford University in 2001. She is currently an Assistant Professor Adjunct in the Department of Anthropology at the University of Colorado, Boulder, and is a member of the Institute of Andean Studies. Her research explores the roles that architecture and the built environment play in the development of human societies, particularly during the Andean formative period. Specifically, she studies the design, construction, and growth of prehistoric monumental architecture using new techniques including three-dimensional digital mapping, computer modeling, systematic spatial analyses, architectural patterning, and direct dating of construction materials. She has conducted research on Chavín de Huántar since 1996, supported by grants from sources including the National Science Foundation, the National Geographic Society Committee for Research and Exploration, and the Howard Heinz Foundation.
