For the stirring overture to Mozart's "Don Giovanni," the arranger separates the layers into different clarinet voices, creating an octet which capably reflects the original. Scored for four B-flat clarinets, two alto clarinets, and two bass clarinets; the first B-flat clarinet can double as an E-flat clarinet, and the first alto clarinet can double as a fifth B-flat clarinet. For a well coordinated ensemble of advanced clarinetists.
