from Ricercare II.
In the second Ricercare the stream of white noise, mapped to a chromatic tonality, produces shorter phrase collections, closer to the length of human language phrases. What we hear is the original pitch patterns reassembled and reordered. The first and second trombones play vivid soloistic passages marked variouslycon brio and con fuoco.
These passages are interrupted by gentle full ensemble chorale-like measures marked sostenuto and leggiero. There is an extensive play of changing metres throughout this ricercare, as though we are listening to actors speak decisively, interrupted by comments from a chorus.
