Sergei Ivanovich Taneyev (Russian: Серге́й Ива́нович Тане́ев, Sergey Ivanovich Taneyev, pronounced [sʲɪˈrɡej ɪˈvanəvʲɪtɕ tɐˈnʲejɪf]; November 25 [O.S. November 13] 1856 – June 19 [O.S. June 6] 1915) was a Russian composer, pianist, teacher of composition, music theorist and author.
Taneyev was born in Vladimir, Vladimir Oblast, Russia, to a cultured and literary family of Russian nobility. A distant cousin, Alexander Taneyev, was also a composer, whose daughter, Anna Vyrubova, was highly influential at court. Alexander was drawn closely to the nationalist school of music exemplified by The Five, while Sergei would gravitate toward a more cosmopolitan outlook, as did Tchaikovsky.
He began taking piano lessons at age five with a private teacher. His family moved to Moscow in 1865. The following year, the nine-year-old Taneyev entered the Moscow Conservatory. His first piano teacher at the Conservatory was Edward Langer. After a year's interruption in his studies, Taneyev studied again with Langer. He also joined the theory class of Nikolai Hubert and, most importantly, the composition class of Pyotr Ilyich Tchaikovsky. In 1871, Taneyev studied piano with the Conservatory's founder, Nikolai Rubinstein.
Taneyev graduated in 1875, the first student in the history of the Conservatory to win the gold medal both for composition and for performing (piano). He was also the first person ever to be awarded the Conservatory's Great Gold Medal; the second was Arseny Koreshchenko and the third was Sergei Rachmaninoff. That summer he travelled abroad with Rubinstein. That year he also made his debut as a concert pianist in Moscow playing Brahms's First Piano Concerto, and would become known for his interpretations of Bach, Mozart and Beethoven. In March 1876 he toured Russia with violinist Leopold Auer.
