Shlomo Dubnov, de la Universidad de San Diego, ofrecerá una charla-demostración sobre composición e improvisación realizadas por maquinas utilizando el sistema OMax. La misma se efectuará el martes 28 de mayo en el Salón 210H, a las 3:00PM. Es abierta al publico y libre de costo. Esta actividad es organizada por el Departamento de Composición y el profesor Alfonso Fuentes.
El profesor Dubnov explica:
“In the talk I will present work on machine intelligence that allows the computer to extract, analyze and create original variations from existing music. This area of research and experimental music practice adds an important tool to more formal methods of algorithmic composition that rely mostly on synthetic algorithms. The tradition of using computers for composition and improvisation relies mostly on models that formalized musical rules or uses models from physics, genetics and other sciences to generate materials according to scientific theories. The problem with synthetic approaches is that they have difficulty capturing or expressing the complexity of humanly composed music, and especially idiomatic aspects of personal style that are almost impossible to formalize.
Over the last 15 years I have been working with colleagues in IRCAM and elsewhere on creating systems that can capture musical style from examples. This lead to emergence of two exiting areas in computer music: 1) Machine Improvisation systems where machine can learn and generate imitations of musician’s style “on the fly”, and 2) Machine Listening, and specifically the area of Music Information Dynamics, where computer analysis can characterize patterns of complexity and predictability in music. My current research deals with trying to combine the two areas, namely allowing the machine both to listen and improvise, a task that is may be natural to humans, but is only now catching up in research on computer applications for composition and improvisation.”
Schlomo Dubnov is graduated from the Jerusalem Music Academy in composition and holds a Ph.D. in Computer-Science from the Hebrew University, Jerusalem. In both institutes he served as a lecturer on computer music. The results of Dubnov’s academic research are regularly published in musical and technical books and journals. In 1996 he received the Distinguished Paper Award from the International Computer Music Association (ICMA) for his work on Polyspectral Analysis of Musical Timbre. In 1996-1998, he worked as an invited researcher in IRCAM – Centre Pompidou (Paris). Since 1998, Dubnov headed the Multimedia track in Communication Engineering Department of Ben-Gurion University, Israel, where he conducted numerous researches on advanced audio processing and retrieval methods, computer music and other multimedia applications. In September 2003 he joins the UCSD Department of Music faculty to meet the needs of the expanding Computer Music and Interdisciplinary Computing in the Arts programs.
