Wolfgang Amadeus Mozart (1756 – 1791) was a prolific and influential composer of the Classical period. Despite his short life, his rapid pace of composition and proficiency from an early age resulted in more than 800 works representing virtually every Western classical genre of his time. Many of these compositions are acknowledged as pinnacles of the symphonic, concertante, chamber, operatic, and choral repertoire. Mozart is widely regarded as one of the greatest composers in the history of Western music, with his music admired for its "melodic beauty, its formal elegance and its richness of harmony and texture". Born in Salzburg, Mozart showed prodigious ability from his earliest childhood. At age five, he was already competent on keyboard and violin, had begun to compose, and performed before European royalty.

The Magic Flute (Die Zauberflöte), K. 620, is an opera in two acts by Wolfgang Amadeus Mozart to a German libretto by Emanuel Schikaneder. The work is in the form of a Singspiel, a popular form during the time it was written that included both singing and spoken dialogue. The work premiered on 30 September 1791 at Schikaneder's theatre, the Freihaus-Theater auf der Wieden in Vienna, just two months before the composer's death. It was the last opera that Mozart composed. The opera was an outstanding success from its first performances, and remains a staple of the opera repertory to this day.

"Ach, ich fühl's, es ist verschwunden" (Pamina's Aria) is sung by the character Pamina, where she expresses her despair and belief that Tamino no longer loves her, feeling that his love has vanished; it's a moment of deep emotional turmoil in the opera signifying her loss of faith in their relationship.
