Haydn's Armida is an opera composed by Joseph Haydn in 1783. It is based on the story of Armida, a sorceress from Torquato Tasso's epic poem, Jerusalem Delivered. The opera features themes of love, magic, and conflict, showcasing Haydn's skill in blending dramatic elements with beautiful music. The work is structured in three acts and includes a variety of arias and ensembles that highlight the characters' emotions and struggles. Although not as widely performed as some of Haydn's other works, Armida remains an important part of his operatic repertoire and reflects the style of the late Classical period.
