It is important to understand that at this point in time there were two main styles of opera, Italian and German. Italian opera was very much a vehicle of good melodies and exciting tunes with less emphasis on drama while German operas was more concerned with drama and perhaps less so with memorable tunes.
In Germany, Beethoven wrote only one opera, first performed in 1805 and called 'Leonore', which after several revisions eventually became known as 'Fidelio'. The opera tells how Leonore, disguised as a prison guard named Fidelio, rescues her husband Florestan from death in a political prison. Listen to the jailer’s aria, ‘If you don’t have any money’, sung by Rocco, a baritone.

In the 1820s Weber produced three operas, ‘Der Freischütz’, ‘Euryanthe’ and ‘Oberon’, and is regarded as being the father of German opera and the most important composer in Germany in the first half of the 19th century. He was quite innovative; he used folk tunes in Der Freischütz and started to use themes to denote particular characters. Among the many composers influenced by Der Freischütz was a young Richard Wagner, who would come to be seen by many as Weber's successor and who used this technique in his operas.

At the beginning of the Romantic period three Italian composers are most important in the development of opera, Rossini, Donizetti and Bellini.
All three composers were renowned for the compositions in the ‘Bel Canto’ (beautiful singing) style of long and smooth melody. Rossini composed his operas right at the start of the Romantic period and in 1817 produced the very successful 'La Cenerentola' (Cinderella), a not serious, but quite touching tale as the main character develops from a folk-song-like scullery maid to a full-blown coloratura soprano when she becomes royalty at the end of the opera. One of the most famous of Rossini's arias is from his comic opera, ‘The Barber of Seville’. The aria, sung by the barber, Figaro, a baritone voice, is a bright and happy sound, ‘I am the barber everyone wants’.

Despite dying at only 34 years of age, Bellini wrote 11 operas in that time, the most famous of which is ‘Norma’. This is full of extremely difficult coloratura arias and few singers have ever really mastered these arias. Listen to this short excerpt of Bellini's aria style.
Towards the end of the 19th century two composers are most important, Verdi in Italy and Wagner in Germany.
