text: The influence of Anton Arensky, who taught Rachmaninoff for five years while he was at the Moscow Conservatory, can be seen in the composer's early compositions. This influence can be seen, for example, in his symphonic poem Prince Rostislav, dedicated to Arensky, and a number of compositions from his student years may have been written as exercises for his teacher. According to biographer Barrie Martyn, the "obviously Russian character" and "Tchaikovskian lyricism" of Arensky's music were elements which were also part of Rachmaninoff's compositional style. Sergei Taneyev, Rachmaninoff's teacher in counterpoint at the Moscow Conservatory, was also an influence on his early compositions, and Rachmaninoff would bring his compositions to Taneyev to gain his approval all the way up to 1915, the year in which Taneyev died. In his later style, the influence of Rimsky-Korsakov can be seen in the increasingly chromatic harmonies and thinner orchestration in Rachmaninoff's compositions from his Third Piano Concerto onwards.
  Works
  Rachmaninoff wrote five works for piano and orchestra: four concertos— in F-sharp minor, Op. 1 (1891, revised 1917),  in C minor, Op. 18 (1900–01),  in D minor, Op. 30 (1909), and  in G minor, Op. 40 (1926, revised 1928 and 1941)—and the Rhapsody on a Theme of Paganini. Of the concertos, the Second and Third are the most popular.
  Rachmaninoff also composed a number of works for orchestra alone. The three symphonies:  in D minor, Op. 13 (1895),  in E minor, Op. 27 (1907), and  in A minor, Op. 44 (1935–36). Widely spaced chronologically, the symphonies represent three distinct phases in his compositional development. The Second has been the most popular of the three since its first performance. Among Rachmaninoff's other orchestral works are his Symphonic Dances (Op. 45), his last major composition, and his four symphonic poems: Prince Rostislav, The Rock (Op. 7), Caprice bohémien (Op. 12), and The Isle of the Dead (Op. 29).
