Silvia Matheus is a Brazilian-born composer and performer working at the intersection of sound, technology, and live performance. Her music integrates fixed media, interactive electronics, and acoustic instruments, often unfolding through improvisation and collaboration with artists working in dance, film, and multimedia performance. Her work explores the relationships between gesture, sound, and space, creating immersive sonic environments that move between composed structures and spontaneous interaction. Early in her career, Matheus developed experimental music controllers made from etched glass and conductive paint, transforming the musical score itself into a performable electronic interface. This work reflects her longstanding interest in integrating visual form, physical gesture, and electronic sound. Matheus received her Master of Fine Arts in Electronic Music and Recording Media from Mills College in Oakland, California. She also participated in seminars on interactive music and performance at the Center for New Music and Audio Technologies (CNMAT) at the University of California, Berkeley, studying with David Wessel. Her early musical training took place in São Paulo, Brazil, where she studied with composer Hans-Joachim Koellreutter. Her work has been presented internationally at major conferences dedicated to electronic and experimental music, including the International Computer Music Conference (ICMC) in Hong Kong; Banff, Canada; Japan; Havana, Cuba; Denmark; and New York, USA. She has also performed at the Kyma International Sound Symposium (KISS) in Brussels, Vienna, Lübeck, St. Cloud, and Santa Cruz. In the late 1990s she received a composition grant to work at the Danish Institute of Electronic Music (DIEM). Her multimedia work Hands, a Taiji-choreographed performance for piano, video, and electronics, was presented in Münster and Cologne, Germany, and in New York and San Francisco as part of the multimedia piano project Handscapes, organized by pianist Jennifer Hymer. In addition to composing and performing, Matheus has contributed reviews to the Computer Music Journal (MIT Press) and has worked extensively in arts documentation as a freelance camera operator and editor, collaborating with theater groups in the San Francisco Bay Area. She currently performs with composer Thomas Miley using computer-based and modular electronic systems. Analogous, an electroacoustic duo formed by Silvia Matheus and Thomas Miley, explores improvisation and evolving sonic environments. Listening and exploration are central to her work, and many of her recent projects are designed as improvisational environments that invite performers to explore sound and real-time interaction with electronic systems. Her music can be heard on SoundCloud and Bandcamp.
