Franck, born in 1822 in what is now Belgium, became a naturalised French citizen in 1871. That year, he was a founding member of the
Société nationale de musique, established in the wake of the
Franco-Prussian War by
Camille Saint-Saëns and
Romain Bussine to promote French music. Franck's works after 1870 reflect his growing awareness of and interest in German music, especially that of
Richard Wagner. Urged on principally by his student
Henri Duparc, Franck "made an effort to study one of the Wagner scores every summer during the last period of his life.". Although he remained ambivalent about Wagner's compositional approach, his estimation of Wagner's merits remained, unlike others in the
Société nationale (notably Saint-Saens) "in no way influenced by the nationalist dimension." He remained an admirer of German music and was less troubled than some of his colleagues about the so-called "L'invasion germanique" of music in France in the 1870s. Indeed, Franck dedicated the symphony "to my friend
Henri Duparc," the student who had principally urged him to deepen his knowledge of Wagner's operas. Franck reached his creative peak in the 1870s, when he was in his late fifties. His
Piano Quintet and the
oratorio Les Béatitudes appeared in 1879, the
Symphonic Variations in 1885 and the
Violin Sonata in 1886. In 1887 he began sketches for a symphony – a musical form more associated with German than with French music. Like Berlioz, Franck revered
Beethoven, and several commentators have noted the influence of Beethoven, particularly the
late string quartets, on the symphony, both as to form – Franck adopted a
cyclic structure – and content. Like Berlioz, Franck departed from the customary four-movement form of the classical symphony of
Haydn,
Mozart and Beethoven; unlike the
Symphony fantastique by Berlioz, which is written in five movements, Franck's symphony is written in three. ==Premiere and reception==
