The period from 1880 to 1917 marked a renaissance in Russian choral music. Previously, Russian choral music had been dominated by German and Italian influences. Now composers returned to old Russian chants as the source of their works, thus creating a thoroughly Russian choral style. Although Sergei Rachmaninov wrote only few choral works, they are among the finest example of Russian choral music ever written. Of those works, the All-Night Vigil (more commonly referred to as the Vespers) stands as his crowning achievement and is widely regarded as the pinnacle of the Orthodox church music as a whole. Composed in 1915, the All-Night Vigil is comprised of texts for services of Vespers, Matins and Prime. In writing the work, Rachmaninov employed a system known as "choral orchestration," which requires singers to make use of a wide range of complex vocal techniques. But for all the innovation and technical prowess evident in Rachmaninov's All-Night Vigil, it is the work's intense emotion and deep spirituality that stays with the listener.
