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.
