Se vuol ballare
The cavatina "" is an aria for baritone or bass from the first act of the opera "The Marriage of Figaro" by Wolfgang Amadeus Mozart. The libretto was written by Lorenzo Da Ponte based on a stage comedy by Pierre Beaumarchais, La folle journée, ou le Mariage de Figaro (1784). The Italian title means "If you want to dance".
Gli equivoci
Following the success of his libretto for "The Marriage of Figaro", Da Ponte was asked by Storace to provide for him a libretto based on Shakespeare. Da Ponte compressed Shakespeare's plot into two acts, but retained nearly all the key elements. "Gli equivoci" was the second of Storace's operas to be performed at the Burgtheater.
