an 1845 opera in three acts, music and text by Richard Wagner, (WWV 70 in the catalogue of the composer's works) based on two German legends: Tannhäuser, the mythologized medieval German Minnesänger and poet, and the tale of the Wartburg Song Contest. The story centers on the struggle between sacred and profane love, and redemption through love, a theme running through much of Wagner's mature work. It is a tragedy.
