A Christmas program with a rare breadth of choral palette: from ancient chants to 20th-century music. Christmas choral music sounds particularly focused and weighty when different eras and traditions converge in the program. On this evening, the focus is on spiritual heritage, constructed like a large musical canvas: from ancient Russian chants to compositions by 20th-century composers. The program begins with the troparia and kontakions of the Nativity of Christ, where a strict line of znamenny and strochnoye polyphony can be heard. Next unfolds the Russian academic tradition: concerts and spiritual compositions by Bortnyansky, Tchaikovsky, Lyadov, Rachmaninoff, Kalinnikov, Sviridov, and Schnittke. These pages show how church text and musical form gradually gained greater expressiveness and scale. The European line is represented by Ave Maria from different eras and styles - from Gregorian chant to Bruckner, Poulenc, and Britten. The comparison of these compositions allows one to hear how differently composers worked with the prayerful word, texture, and choral sound. The program concludes with works by Stravinsky, where folk texts and a female vocal ensemble give the evening a special rhythmic and intonational sharpness.
