Félix Rienth is a Swiss operatic tenor. Born in Basel, he was a member of the Basel Boys Choir in his youth. He made his first opera appearance as a boy with Theater Basel as the first boy in Wolfgang Amadeus Mozart's The Magic Flute. He attended the University of Basel, where he earned diplomas in the Spanish and German languages. He then studied singing privately in Basel with Heidi Wölnerhanssen before entering the Hochschule der Künste Bern; graduating from there in 2000 with a degree in opera performance. He has since had a major career as a concert singer in the oratorio repertoire; appearing with important ensembles and at major music festivals throughout Europe, including a recital in presence of Her Majesty, Queen Fabiola of Belgium. He has made about 20 recordings on a variety of labels. A highly acclaimed production was the recording of Johann Christoph Pepusch's "Tenor Cantatas" with his wife, Muriel Rochat Rienth, recorder player, and Swiss baroque ensemble "La Tempesta Basel".
