Wagner
Wilhelm Richard Wagner (1813-1883) was a German composer, conductor, theatre director and essayist, primarily known for his operas (or "music dramas", as they were later called). Unlike most other opera composers, Wagner wrote both the music and libretto for every one of his works. One of the most popular wedding marches played as the bride's processional in English-speaking countries, popularly known as "Here Comes the Bride", takes its melody from the "Bridal Chorus" from Lohengrin. In the opera, it is sung as the bride and groom leave the ceremony and go into the wedding chamber.
