The cor anglais is a transposing instrument pitched in F, a perfect fifth lower than theoboe (a C instrument). This means that music for the cor anglais is written a perfect fifth higher than the instrument actually sounds. The fingering and playing technique used for the cor anglais are essentially the same as those of the oboe and oboists typically double on the cor anglais when required. The cor anglais normally lacks the lowest B key found on most oboes and so its sounding range stretches from E3 (written B) belowmiddle C to C6 two octaves above middle C.

Martha (opera) – Wikipedia

Martha, oder Der Markt zu Richmond (Martha, or The Market at Richmond) is a romantic comic opera in four acts by Friedrich von Flotow set to a German libretto by Friedrich Wilhelm Riese and based on a story by Jules-Henri Vernoy de Saint-Georges.

Flotow had composed the first act of a ballet, Harriette, ou la servante de Greenwiche, derived from a text by Saint-Georges, for the ballerina Adèle Dumilâtre. This was first performed by the Paris Opera Ballet at the Salle Le Peletier on 21 February 1844. The time available for the composition was short, so the second and third acts were assigned, respectively, to Friedrich Burgmüller and Édouard Deldevez. The opera Martha was an adaptation of this ballet.[1]
