Alena Baeva took her first violin lessons at the age of five with Professor Olga Danilova, before moving to Moscow, Russia, at the age of 10 to study with Professor Eduard Grach at the Central School of Music and the State Tchaikovsky Conservatoire. In addition to her formal education, she took lessons in Paris with Mstislav Rostropovich and Boris Garlitsky, in Switzerland with Seiji Ozawa, and in Israel with Shlomo Mintz (at Keshet Eilon Music Center).

Alena Baeva is a citizen of Luxembourg. She plays on the “ex-William Kroll” Guarneri del Gesù of 1738 (on generous loan from an anonymous patron, with the kind assistance of J&A Beares).
