Pilgerchor aus Tannhäuser, S. 676

Tannhäuser is an 1845 opera in three acts, with music and text by Richard Wagner (WWV 70 in the catalogue of the composer's works). It is based on two German legends: Tannhäuser, the mythologized medieval German Minnesänger and poet, and the tale of the Wartburg Song Contest. The story centres on the struggle between sacred and profane love, as well as redemption through love, a theme running through most of Wagner's work.
The opera remains a staple of major opera house repertoire in the 21st century.
