Charles-Valentin Alkan's "Impromptu sur le Choral de Luther: Un fort rempart est notre Dieu, Op. 69" is a piano work that was composed in 1861. The piece was premiered in Paris in the same year, and it is one of Alkan's most well-known works. The piece is structured in three movements, with the first and third movements being fast and virtuosic, while the second movement is slower and more contemplative. The first movement is marked "Allegro assai," and it begins with a series of rapid arpeggios that set the tone for the rest of the piece. The main theme is then introduced, which is based on the Lutheran hymn "Ein feste Burg ist unser Gott" (A Mighty Fortress Is Our God). The theme is developed throughout the movement, with Alkan showcasing his technical prowess through a series of intricate runs and flourishes. The second movement is marked "Andante con moto," and it provides a contrast to the first movement with its more introspective and lyrical character. The main theme is introduced in the left hand, while the right hand provides a delicate accompaniment. The theme is then developed through a series of variations, with Alkan exploring different textures and harmonies. The third movement is marked "Allegro moderato," and it returns to the virtuosic character of the first movement. The main theme is reintroduced, and Alkan once again showcases his technical prowess through a series of rapid runs and arpeggios. The movement builds to a frenzied climax before ending with a triumphant flourish. Overall, "Impromptu sur le Choral de Luther: Un fort rempart est notre Dieu, Op. 69" is a challenging and impressive work that showcases Alkan's technical skill and musical imagination. Its use of the Lutheran hymn as a basis for the main theme adds a spiritual dimension to the piece, while its virtuosic character makes it a favorite among pianists and audiences alike.
