 The fusion of dramatic music , melodramatic plot , and <unk> staging in Robert le diable proved a sure @-@ fire formula , as did the partnership with Scribe , which Meyerbeer would go on to repeat in Les Huguenots , Le prophète , and L 'Africaine . All of these operas held the international stage throughout the 19th century , as did the more pastoral Dinorah ( 1859 ) , making Meyerbeer the most frequently performed composer at leading opera houses in the nineteenth century .
