Oak, the evergreen from the Ghigi Park in Ariccia near Rome

Wilhelm Richard Wagner was a German composer, theatre director, essayist, and conductor, best known for his operas, although his mature works are often referred to as music dramas. Unlike most composers, Wagner wrote both the libretti and the music for all of his stage works. He first achieved recognition with works in the Romantic tradition of Carl Maria von Weber and Giacomo Meyerbeer, but revolutionised the genre through his concept of the Gesamtkunstwerk, which sought to unite poetic, musical, visual, and dramatic elements. In this approach, the drama unfolds as a continuously sung narrative, with the music evolving organically from the text rather than alternating between arias and recitatives. Wagner outlined these ideas in a series of essays published between 1849 and 1852, most fully realising them in the first half of his four-opera cycle Der Ring des Nibelungen.
