are simple, or slightly modified, strophic settings. Some, such as his best-known song "Auf Flügeln des Gesanges" ("On Wings of Song"), became popular. The scholar Susan Youens comments "If [Mendelssohn]'s emotional range in lied was narrower than Schubert's, that is hardly surprising: Schubert composed many more songs than Mendelssohn across a wider spectrum", and whilst Schubert had a declared intent to modernize the song style of his day, "[t]his was not Mendelssohn's mission." A number of songs written by Mendelssohn's sister Fanny originally appeared under her brother's name; this may have been partly due to the prejudice of the family, and partly to her own retiring nature. In 1842, this resulted in an embarrassing moment when Queen Victoria, receiving Felix at Buckingham Palace, expressed her intention of singing to the composer her favourite of his songs, Italien (to words by Franz Grillparzer), which Felix confessed was by Fanny. Performer During his lifetime, Mendelssohn became renowned as a keyboard performer, both on the piano and organ. One of his obituarists noted: "First and chiefest we esteem his pianoforte-playing, with its amazing elasticity of touch, rapidity, and power; next his scientific and vigorous organ playing [...] his triumphs on these instruments are fresh in public recollection. In his concerts and recitals Mendelssohn performed works by some of his German predecessors, notably Carl Maria von Weber, Beethoven and J.S. Bach, whose organ music he brought back into the repertoire "virtually alone". Mendelssohn admired the grand pianos of the Viennese maker Conrad Graf; he acquired one in 1832 which he used in the family house and recitals in Berlin, and later another for use in Düsseldorf. In private and public performances, Mendelssohn was celebrated for his improvisations. On one occasion in London, when asked by the soprano Maria Malibran after a recital to extemporise, he improvised a piece which included the melodies of all the songs she had sung. The music publisher Victor Novello, who was present, remarked "He has done some things that seem to me impossible, even after I have heard them done." At another recital in 1837, where Mendelssohn played the piano for a singer, Robert Schumann ignored the soprano and wrote "Mendelssohn accompanied like a God." Conductor Mendelssohn was a noted conductor, both of his own works and of those by other composers. At his London debut in 1829, he was noted for his innovatory use of a baton (then
