Invention was composed for oboist Lindsey Reymore
. It frequently switches between 3/4 and 6/8 — a hemiola taken to the point that there isn’t a clear dominant meter. The first motive is a five-note figure explored in various rhythmic configurations. The second is a more reflective figure with repeated notes. Canons are a recurring idea — a canon begins the piece, a canon at inversion begins the recapitulation, and another canon begins the coda.
