Sénéchal also appeared regularly in operettas, especially by Offenbach, such as "Orphée aux enfers", "La Vie parisienne", "La Périchole", where his comic talent was shown to fine effect. As the years went by Sénéchal started concentrating on character roles such as Basilio in "Nozze di Figaro", Goro in "Madama Butterfly", the innocent in "Boris Godunov", Monsieur Triquet in "Eugene Onegin", and the four servants in "Les contes d'Hoffmann", which were his debut roles at the Metropolitan Opera on 8 March 1982.
