Ivan Kostyakhin studied in Minsk, at the Belarusian State Conservatory (today is the Academy of music), as an opera and symphony conductor, also a conductor-choirmaster. The interest in ensemble and choral music of different periods and styles as well as in Russian spiritual music was promoted by the teaching of Viktor Rovdo, professor, People's Artist of the USSR, the continuer of the tradition of Russian and East Slavic choral music coming from A. Sveshnikov. Acquaintance with the creativity of a major Russian conductor, professor, People's Artist of Russia Gennady Provatorov determined the future of Ivan Kostyakhin on the way of the opera and symphony conducting. After receiving the Master of Arts degree in choral conducting in 2001, Ivan continued his education in the class of professor Gennady Provatorov, one of the major specialists in the field of Russian symphonic and opera music.
