The Frankfurter Opern- und Museumsorchester (Frankfurt Opera House and Museum's Orchestra) is the resident orchestra of the Oper Frankfurt. Its somewhat peculiar name is derived from the series of "Museum Concerts", organized by the Frankfurter Museumsgesellschaft since 1808.[1] The orchestra is ranked as an "A-list" ensemble under the German TVK regulations. Its music director and principal conductor is Thomas Guggeis.
