EXPRESSIVE GESTURE : A TECHNIQUE FOR THE USE OF GESTURE DESCRIPTORS IN ALGORITHMIC IMPROVISATION

(2019)

Music often conveys a sense of “gesture”, anevocation of motion and energy, which makes it dramatic, exciting, and expressive. One common challenge in the production of algorithmically-generated computer music is the question of how to imbue the sound with the excitement and vitality of liveperformance. In the case of interactive computer music, one has the additional challenge of programming the computer to interpret the expressive qualities of musicbeing performed in real time. This lecture presents an approach to automaticallyanalyzing and characterizing gesture in musical sound, as a way of improving a computer’s interaction with a human performer in a live improvisation. By describing music as patterns of changing parametric data, the computer can store and categorize descriptors of musical gestures. As an extension of that research, we can then consider how derivatives of that analysis data—the ways in which the data changes over time—characterize thegestural quality of a performance. In the algorithmic generation of music, control of those derivatives of change in musical parameters can improve the expressivepotential of computerized improvisation.

Intentional Inclusion :Promoting Diversity in Graduate Study of Music Technology

(2017)

A lack of diversity among faculty and students in graduate programs that focus on music technology and computer music may unwittingly discourage participation by certain segments of the population, and thus may hinder the development of a potentially wide variety of ideas andaesthetics. Graduate student numbers of women and minorities in the field are proportionally low. In the absence of any concerted plan of action to diversify such programs, this state of affairs is not likely to change. What can be done to increase diversity among people succeedingin the academic fields of music technology, in the interest of hybrid vigor and social justice? By pursuing a conscientious policy of intentional inclusivity, some progress may be made toward rectifying imbalances, thus enhancing diversity of scholarship and creative work. This article makes an assessment of demographic imbalances and proposes some concrete steps facultymay be able to take toward improvement.
