Weber's eerily fantastical Der Freischütz is heralded as one of the cornerstones of Romantic opera, being the first in operatic history to draw on traditional German folk tunes and elements of Romanticism. The evocative and colourful orchestration of the 'Wolf's Glen' scene, the most gruesomely expressive rendering of evil ever found in a musical score, is particularly impressive. Much of the music is instantly familiar: several of the melodies have been adapted as hymn tunes, and the Overture regularly appears in the concert hall.
