Il Guarany: Overture is the orchestral overture to the opera Il Guarany by Brazilian composer Antônio Carlos Gomes, composed and premiered in 1870. The music exemplifies late-Romantic orchestral writing with lyrical melodies, sweeping string lines and colourful orchestration that blends European operatic technique with motifs inspired by Brazilian themes, and it occupies an early, prominent place in Gomes's output following the opera's premiere.
