Children's choir, pure and clear treble voices, no vibrato, soft consonants, warm and nostalgic atmosphere. Gentle acoustic guitar plucking and soft string pad in the background. Slow tempo, 70 BPM. Verses are sung in unison quietly (piano). Chorus expands into gentle two-part harmony, wide and bright (mezzo-forte). Bridge is whispered and intimate (pianissimo). Final chorus is powerful, full choir with a sense of wonder and a hint of distant bell-like synth (forte). Cinematic, lullaby-like, peaceful, evokes the feeling of a summer evening in an ancient Russian city. Reverb like a large stone cathedral hall.
