Puccini's famous "Nessun Dorma" is an aria that takes place during the final act of the opera Turandot. The prince Calaf, despite having answered the titular character's riddles (and thus avoiding execution), is still spurned by Princess Turandot. Undeterred and completely in love, Calaf offers her a way out: if she can guess his name by dawn, he will submit to execution. If not, she must marry him. Desperate to avoid marriage, Turandot in her cruelty orders no one to sleep ("Nessun Dorma") until someone reveals Calaf's name. If her subjects fail, they will all be killed. Dawn quickly approaches, and Calaf becomes sure of victory, which he expresses joyfully at the end of the aria.
While sharing many characteristics with Grade 2 pieces, this arrangement tests the ranges of Parts 2 and 3, thus justifying the increase in difficulty level. Part 4 is not particularly adventurous, but the challenge will lie in providing a strong foundation of balance and musicality for the rest of the ensemble to build on. This arrangement provides an opportunity for trombones to strengthen their command of 7th position.
