Composed in 2006, this work for solo clarinet takes as it starting point the separation of three different musical ideas based around character (rhythmic and pulsed, flowing and melodic, static ‘dirty’ and irregular), register (high, low, angular) and their own evolution and profile. The form of the piece arises from the shaping and progress of these lines within their own acoustic spaces; the overall change from stasis and angularity to linear and regular material. The idea for the pieces is loosely based on the types of energy and gesture expressed in Stravinsky’s Trois Pièces pour clarinet; in Upon Convergence these types are combined and superposed in a single continuous form, rather than appearing within three discrete utterances.
