Ferdinand Ries was a German composer. Born into a musical family of Bonn,[a] Ries was a friend and pupil of Beethoven who published in 1838 a collection of reminiscences of his teacher, co-written with Franz Wegeler. He was also a composer who left eight symphonies, a violin concerto, eight piano concertos and numerous other works in many genres, including 26 string quartets. Of these, the symphonies, some chamber works—most of them with piano—and his piano concertos have been recorded, demonstrating a style which is not surprisingly somewhere between those of the Classic and early Romantic eras.
