About Alexander Tcherepnin
Alexander Nikolayevich Tcherepnin (Russian: Алекса́ндр Никола́евич Черепни́н, romanized: Aleksandr Nikolayevich Cherepnin; 21 January 1899 – 29 September 1977) was a Russian-born composer and pianist. His father, Nikolai Tcherepnin (pupil of Nikolai Rimsky-Korsakov), and his sons, Serge Tcherepnin and Ivan Tcherepnin, as well as two of his grandsons (sons of Ivan), Sergei and Stefan, were composers. His son Serge was involved in the earliest development of electronic music and instruments. His mother was a member of the artistic Benois family, a niece of Alexandre Benois. == Biography == He was born in Saint Petersburg, Russia, and played the piano and composed prolifically from a very early age. He was stimulated in this activity by the atmosphere at home, which—thanks to his family's Benois-Diaghilev connection—was a meeting place for many well-known musicians and artists of the day. By the time he began formal theory and composition studies in his late teens, he had already composed hundreds of pieces, including more than a dozen piano sonatas. Among his teachers in Russia were composer Victor Belyayev (pupil of Anatoly Lyadov and Alexander Glazunov), who prepared Tcherepnin for Saint Petersburg Conservatory; Leokadiya Kashperova (renowned pianist, protégée of Anton Rubinstein); and his professor at the Conservatory Nikolay Sokolov (pupil of Nikolai Rimsky-Korsakov). Notably at that time Tcherepnin's mentor was famous musicologist Alexander Ossovsky, who also was a friend of his father. His works were influenced by composer Alexander Spendiarov.
