The Queen of the night aria from Mozart's 'The Marriage of Figaro' opera is a challenging aria for a soprano.

An 'aria' -- literally "air" in Italian, meaning song or melody. This would be the most direct answer, but others are a possibility: "arioso", recitative, or the pairing of a "cavatina" and "cabaletto" which together form an entire "scena" (scene) for a singer.

Many opera terms are in Italian, or derived from Italian, due to the importance of the Italians in music during the 15th and 16th centuries. The first Opera is often thought to be L'Orfeo by Claudio Monteverde .
