The title Resonance derives from the sound created by imposing two major triads on top of each other, eg. the first brass chord of F major over G major, otherwise an eleventh chord. The whole piece is then worked out through these intervals, opening with a rush of flourishes and fanfares creating a lively atmosphere, moving to a middle slower section with a more angular melody. the opening is repeated and leads to a flying CODA with a cheeky interchange between Oboe and Piccolo.
