Interpretation of Beethoven's Fidelio or Leonore and four different overtures

Research Paper (undergraduate) from the year 2010 in the subject Sociology - Media, Art, Music, The University of Malaya, language: English, abstract: Written with librettist, Joseph von Sonnleithner, Beethoven's first version was divided into three acts in the style of a German Singspiel. In a singspiel, a fresh start has to be made after every spoken interruption. Fidelio was first performed on November 20, 1805 after being delayed due to issues with the censors.

It took Beethoven over a decade to complete his only opera. Throughout the many revisions he produced four different overtures.
