Carl Maria von Weber (1786-1826) is known to many as the composer of ‘Invitation to the Dance’, a piano piece that became well-known in the version orchestrated by Hector Berlioz. It was used as the music for the Ballets Russes ballet Le spectre de la rose. Far more significant to music history, however, is Weber’s opera Der Freischütz. Premièred in Berlin in 1821, Der Freischütz was an instant success and brought Weber to the attention of audiences in Germany and beyond. The orchestra plays a prominent role in Der Freischütz and is crucially important in creating atmosphere and building tension. In this and other respects the work was tremendously influential on later composers including Richard Wagner.
