Francesc Viñas is regarded as a Wagnerian tenor par excellence.

Born in Moià in 1863 and died in Barcelona in 1933, he made his début in 1888 at the Liceu with Lohengrin.

Viñas was one of the most internationally-renowned Catalan opera singers of his day, primarily due to his performances of Wagnerian characters, which he sang at the leading opera houses in Europe and America, including La Scala in Milan and New York's Metropolitan – where he debuted in 1894 – as well as London, Philadelphia, Boston, Chicago, Genoa and Naples.

In 1913 he premièred Parsifal in Spain in what was the first time this opera was performed outside Bayreuth. Despite his specialisation in the Wagnerian repertoire (Lohengrin, Tannhäuser, Tristan und Isolde), Viñas also sang Italian and French opera (Aida, Lucia di Lammermoor, Cavalleria Rusticana, L’Africaine, etc.).

He was also a writer, both as a correspondent in Rome for the Barcelona newspaper El Noticiero Universal and as a publisher of treatises such as Leyendas del Santo Grial y de Parsifal (1934) and the volume El Arte del Canto (1932, reissued in 1963), based on his experiences as a singer.
