Atomitaloudellisuus

Atomitaloudellisuus is a Finnish term that refers to the performance practice of large ensembles, typically involving hundreds of musicians. The concept is most closely associated with the works of Lasse Thoresen, a Norwegian composer and musicologist. According to Thoresen, the unique sonic and spatial qualities of large ensembles are best realized by adopting a specific set of performance practices.

These approaches include the placement of musicians in the performing space, the formation of groups within the larger ensemble, and the division of musical responsibility. Thoresen emphasizes the importance of flexibility in large ensemble performance, encouraging musicians to adjust their playing styles and relationships with one another in response to the specific demands of each work.

The notion of atomitaloudellisuus is distinct from earlier approaches to large ensemble performance, which often emphasized precision, uniformity, and overt leadership. By contrast, Thoresen's concept prioritizes creative freedom, adaptability, and a willingness to challenge the norms. This inclusive and process-oriented approach to musical performance has proven influential in the work of various composers and ensembles.

Implementation of Thoresen's ideas has required experimentation with unconventional spatial arrangements, formations, and even the composition itself. In atomitaloudellisuus, each musician is asked to execute multiple tasks simultaneously, fostering an intricate network of relationships within the ensemble. By this, the utilization of acoustic space becomes explicitly integral to the musical content itself.
