Virtuosi consists of a single movement divided into two continuous sections each characterised by a particular mood. The opening section creates a serene and mysterious atmosphere with the clarinets introducing a warm smooth melody which naturally flows towards a passage containing much ornamentation. A calmato brings the first section to a close giving the soloist the opportunity to reveal the warm tones of the low chalumeau register. The second section begins with a sequence of rhythmic dynamic sound effects which lead into a virtuoso passage from the soloist. The lively passage then softens to let a short theme introduce the majestic and brilliant finale.
