Prägnanz for Orchestra

by Simpson, Robert R

Prägnanz is a single movement composition for orchestra. This composition reflects the influence of minimalist composers such as Phillip Glass and Steve Reich. The structure of the piece is generated by a rhythmic motive that is transformed through a large-scale additive process. This overarching process is periodically interrupted by contrasting episodes, creating a form similar to a rondo. Several themes and gestures are explored, including a phasing rhythmic motive. The harmonic language is static, almost monolithic, in order to accentuate the gradual motion of the piece towards its goal. The title comes from Gestalt psychology; the Law of Prägnanz describes how the mind perceives simplicity within the complexity of reality. This tendency is mirrored in the piece through the focus on the central motivic transformation in spite of the complexity of contrasting themes, orchestrations, and gestures.
