RACHMANINOFF, Sergei Vasilyevich (1873-1943). Autograph musical quotation signed ("S. Rachmaninov"), Dresden, 28 March 1907. 1 page, oblong 2 7/8 x 4 3/8 in., in giltwood frame. Rachmaninoff boldly pens a full five bars from his Vorspiel Franceska, Op.25, in ink on a hand-drawn stave. With a portrait photograph of Rachmaninoff. 6 3/8 x 4 5/8 in., with photographer's name Mishkin NY in bottom right-hand corner. A well-known colored photograph of one of the greatest pianists of his generation, taken in profile and seated at the keyboard, utterly absorbed in his playing. During this period, Rachmaninoff was in Moscow working as conductor of the Imperial Opera (1905-06) and of the Philharmonic concerts (1911-13), as well as a concert pianist. As a composer, his music, especially his piano compositions, are characterized by the dramatic effects achieved by dark and massive chords, as in his best-known works the second (1901) of his four piano concertos and the Prelude in C Sharp Minor (1892).
