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 Governorate, Russian Empire, 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.
