Many of the concertos written in the early 20th century belong more to the late Romantic school than to any modernistic movement. Masterpieces were written by Edward Elgar (a violin concerto and a cello concerto), Sergei Rachmaninoff and Nikolai Medtner (four and three piano concertos, respectively), Jean Sibelius (a violin concerto), Frederick Delius (a violin concerto, a cello concerto, a piano concerto and a double concerto for violin and cello), Karol Szymanowski (two violin concertos and a "Symphonie Concertante" for piano), and Richard Strauss (two horn concertos, a violin concerto, "Don Quixote"—a tone poem that features the cello as a soloist—and among later works, an oboe concerto).
