THE FIRST KATHISMA IN EARLY RUSSIAN CHANT TRADITION
The research focuses on the fi rst Kathisma of the Vigil in the early Russian chant tradition according to the liturgical indications of Russian recensions of the Jerusalem Typikon. Chant books present two melodic versions of the chants of the fi rst Kathisma that may be described as the early and the main versions. Comparative analysis of the melos of these chants and other liturgical chants belonging to various traditions leads to the conclusion that melodic formulas both of Znamenny chant and Putevoi chant and the special formulas of psalmic octomodal are employed in the melos of the fi rst Kathisma.
