The 2021–2022 CORE Project (Composer-performer Orchestration Research Ensembles) at McGill University brought together three composers, a conductor, and a seven-piece ensemble for a collaborative research-creation process. This paper presents an analysis of the three pieces written during CORE 2 by composers Anita Pari, Louis-Michel Tougas, and Jihyoung Lee. The analysis focuses primarily on the role of the string instruments—both their role within the section and as related to other instruments—in terms of timbre and orchestration. Orchestrational phenomena are described and labeled using the orchestral grouping effects taxonomy developed by Stephen McAdams, Meghan Goodchild, and Kit Soden. In conclusion, the author offers a reflection on the impact her participation as the violinist of McGill’s CORE 2 has had on her life as a contemporary-music performer and pedagogue.
