The Baroque, which manifested itself in Muscovy during the course of the seventeenth century, has been recognized as one of the most dynamic and influential eras of Russian musical and artistic creativity. When looking at the history of Russian music one has a tendency to equate the new stylistic trends of the second half of the seventeenth century with those of the highly westernized eighteenth, and to dismiss both merely as periods of Western imitation. In reality music manuscripts reveal otherwise, and now that compositions are finally becoming available in transcription we realize that an entire era remains to be recognized and re-evaluated. In art and architecture, that era, known as the ‘Moscow’ or the ‘Naryshkin’ Baroque, is distinguished by a blend of Italian, Dutch, Russian, Ukrainian and Bielorussian features in a style that, although influenced by foreign elements, was none the less distinct from any in existence at the time. The Moscow Baroque embraced many aspects of the arts, from iconography, architecture and the applied arts to literature and music. Endorsed by Tsar Alexei Mikhailovich (1645–76), foreign influence began to penetrate Muscovy, ushering in a cognizance of Western concepts that began to clash with the rich and long-established spiritual and cultural traditions. In fact Muscovy was just emerging from an aesthetic explosion known as the Golden Age of national artistic expression. Familiar are the magnificent onion-dome churches that were created during the sixteenth century and the flourishing musical centres in Novgorod and Moscow, where composers and singers developed an intrinsically Russian musical style. This was also the age of indigenous Russian polyphony (e.g. strochnoe moskovskoe, strochnoe novgorodskoe, znamennoe and demestvennoe mnogogolosie) which preceded the wave of Western infiltration that inadvertently led to an untimely halt of the evolutionary process of national awakening. Prior to that halt, the Moscow Baroque stands as a brief but unique chapter in the development of the Russian choral tradition.
