Rigoletto is an opera by Giuseppe Verdi about the amorous Duke of Mantua and his hunchbacked jester Rigoletto. The opera opens with the Duke plotting the seduction of a young beauty he met in church while gossips whisper that Rigoletto has found a mistress and mock his deformity. An assassin offers to rid Rigoletto of a man whose words cut especially close to the heart and it turns out that the clown has a beautiful daughter.

This is the source of La Donna è Mobile, one of the most famous opera tunes. Beautiful music and tragic love, what else does an opera need?

Tropes used in Rigoletto include:
