Fragment of a performance of the Orenburg chamber choir on the solemn act devoted to the 1030 anniversary of the Christianization of Kievan Rus'. Sergey Rachmaninov "To the virgin Devo, rejoice" the All-night vigil. Soch.37.

"In the written "Night service" Rachmaninov uses original melodies of znamenny, Greek, Kiev singsongs. Having creatively apprehended traditions of national polyphony, crowd scenes from operas by Mussorgsky, church chants of Alexander Kastalsky, Rachmaninov finds an ideal ratio between silent contemplation and a passionate statement, severity of a form and whimsical variability of musical subjects, an orthodox canon and absolute creative freedom..."
