Three connected movements each with their own character. Prelude is energetic and riving, featuring highly syncopated melodies and frequent changes of key and phrase length. The central Toccata is a series of traditional cadenzas for cornet and euphonium that ends in a virtuoso duet for the two soloist and leads directly into the Fugue. The baroque-style fugue keeps breaking out into episodes of 'Swingle' bebop. The conflicting styles both vie for pre-eminence but are eventually happily reconciled and combined to bring this piece to a close.
