| Section | Key | Tempo | Main Elements | |---------|-----|-------|----------------| | | D minor | 68 BPM | Finger‑picked acoustic guitar, subtle field recordings of rain, Ekaterina’s a cappella vocal line (no lyrics, wordless “ooh‑ah” textures). | | B (Pre‑Chorus/Build) | G major | 78 BPM | Gradual addition of synth pads, low‑pass filtered drum machine, Sergei’s processed vocal chops. | | C (Drop/Climax) | B♭ minor | 120 BPM | Aggressive 808 sub‑bass, glitch‑percussion, a distorted vocal duet (Ekaterina sings in Russian, Sergei replies in English). | | B (Re‑Build) | Returns to G major | 78 BPM | Stripped back to synth pads and echo‑laced vocal harmonies; introduces a spoken‑word bridge. | | A (Outro/Resolution) | D minor (modulates to D major) | 68 BPM | Acoustic guitar re‑appears, now accompanied by a warm analog synth, Ekaterina’s voice resolves in a lyrical refrain. |
