The Lenten program addresses ancient Russian and Byzantine chants, in which concentration, inner strength, and the beauty of an ancient tradition can be heard. This concert reveals spiritual music as a living art - deep, multilayered, and precise in intonation. Ancient Russian church singing remains an almost unknown territory for many, although it preserves a vast layer of musical culture connected to the centuries-old history of Rus and Byzantine heritage. This Lenten program allows one to hear such a tradition not as a museum rarity, but as a living art, where strictness, depth, and rare expressiveness come together. At the center of the evening are chants dedicated to the period of Great Lent and Holy Week, a time of special concentration and inner silence. The ensemble "Asmatikon" introduces listeners to two major singing lines - ancient Russian and Byzantine. Such music requires special vocal technique, as medieval chants are arranged much more complexly than they may seem at first glance. The performers work with material that cannot be fully conveyed through modern notation. This is why such concerts are especially important: they allow one to hear what is rarely encountered in ordinary concert practice and requires not only professional preparation but also a deep understanding of the tradition. The program covers the entire Lenten period - from the preparatory weeks to Holy Saturday. Special attention is given to the chants of Holy Week, considered some of the most significant pages of ancient Russian singing art. The evening will unite Byzantine chant, znamenny singing, demestvennoye polyphony, and strochnoye polyphony. The program will feature "Behold, the Bridegroom Comes at Midnight", "By the Rivers of Babylon", "Lord, I Have Sinned Much", "Today He Hangs on the Tree", the Cherubic Hymn, the Praises of Holy Saturday, and other chants.
