ABSTRACT In an attempt to begin to redress the relative lack of literature focused on rhythm in acousmatic music, this article is intended as a brief look at the acousmatic perspective on rhythm. The article begins with a quick overview of discussion around rhythm in electroacoustic music in general, then contrasts this with some of Pierre Schaeffer’s views on rhythm and finally compares the perceptual temporal levels identified by Schaeffer with similar levels drawn from electroacoustic music, contemporary music and cognitive psychology.
