Aside from his only opera Fidelio, Beethoven's general link with the theater in Vienna came about largely with incidental music or songs to be inserted into the works of other composers- insertion arias. Konig Stephan was written to celebrate the politically significant opening of a new theatre in Pest, it's triumphant mood honoring the ruling Austrian Emperor. Standard Bearer of female heroism Leonore Prohaska is commemorated with a Soldier's Chorus and a Romance with harp accompaniment. In Friedrich von Matthisson's poem Opferlied ('Sacrificial Song'), a young man prays to Zeus to bestow upon him beauty and goodness in youth and old age. Two of Beethoven's four settings are heard on this wide-ranging programme.
