Guy Chauvet (2 October 1933 – 25 March 2007) was a French operatic singer in the tenor register, regarded as a Heldentenor. He was the only tenor to cover three octaves, from high D5 in chest voice to the low bass D2. Measured in the laboratories of the Fiat factories, his voice produced a sound of 140 decibels.
Born in Montluçon, Chauvet discovered his voice at the age of sixteen during a local party. At Cannes in 1954, he was the youngest member of the tenor competition and one of five prizewinners, with Alain Vanzo, Tony Poncet, Roger Gardes and Gustave Botiaux.
He started at the Palais Garnier as an Armored Man in The Magic Flute on 12 January 1959. To begin with, he held third roles in Aida with Renata Tebaldi and Rita Gorr and also in Samson et Dalila with Mario Del Monaco. He became the youngest tenor of the Paris Opera in the role of Faust in La Damnation de Faust on 20 September 1959. He has the same singing teachers as Georges Thill. His career as a strong tenor was thwarted by his teachers, and he only acquired his C at the age of 32.
Régine Crespin, Fiorenza Cossotto (with whom he sang Samson and Delilah), Gabriel Bacquier and Jon Vickers all worked with him, and he regarded Andréa Guiot as a sister. After a performance of Samson and Delilah at the Metropolitan, he obtained a standing ovation from the audience.
Guy Chauvet distinguished himself above all by the power of his emission, the timbre remaining clear and coppery throughout the whole range. He specialized in wide-ranging roles such as Faust of la damnation, Samson, Pagliacci, Otello, Radamès, Enée, Sigmund, Lohengrin, around the world and above all in performances with the Deutsche Oper Berlin. He was also the advocate of such little known operas as Cherubini's Les Abencérages.
