This is a video recording of a workshop presented by Michael Schutz and Nexus at the LIVE Lab at McMaster University in Hamilton, Ontario on March 6, 2020 titled “What really happens in Steve Reich’s Drumming.” In the workshop, Michael and Russell Hartenberger describe their study that analyzed the first phase in Drumming to determine the relationship of the moving part to the steady part. Russell gives some historical background to the piece and Michael describes the technical aspects of the analysis. Members of Nexus demonstrate phasing on bongos and discuss their thoughts on the process. Additional information on the project can be found in Russell’s article “Anatomy of a Phase” in his book, Performance Practice in the Music of Steve Reich, and at https://maplelab.net/reich/.
