Indie folk with epic development, 104 BPM, key of D major. Russian lyrics. Male vocals: restrained and narrative in the verses, more open and confident in the choruses. Instrumentation: acoustic guitar (chords + fingerpicking), cello for depth, light shakers and cajon for percussion. Add string backing lines in the chorus to emphasize the grandeur of the “border of worlds” concept. In the third chorus, introduce a slight dynamic lift: add a second voice in harmony and a slightly denser bass. Outro: cello motif and fading acoustic guitar, leave a sense of a journey and a path ahead.
