Un bel dì, vedremo

"Un bel dì, vedremo" (Italian pronunciation: [um bɛl di veˈdreːmo]; "One fine day we'll see") is a soprano aria from the opera Madama Butterfly (1904) by Giacomo Puccini, set to a libretto by Luigi Illica and Giuseppe Giacosa. It is sung by Cio-Cio San (Butterfly) on stage with Suzuki, as she imagines the return of her absent love, Pinkerton. It is the most famous aria in Madama Butterfly, and one of the most popular pieces in the entire soprano repertoire.
