Deep, warm, low-register male lead vocal with a rich baritone tone, intimate and emotional in the verses. Add a soft, angelic female vocal only in the choruses, singing harmonies and selected lead phrases. The female voice should be airy, delicate and supportive, never overpowering the male vocal. No female vocal in the verses. Smooth duet feeling in the chorus only.Male verses only: deep, warm baritone voice with subtle Caucasian melismas, expressive but restrained. Chorus: introduce a soft, tender female vocal with breathy harmonies and occasional unison on key lines ("Остаётся любить", "Если после тебя..."). The female voice should feel like light and hope, blending naturally with the male voice. No female vocals before the first chorus. Avoid high-pitched male vocals. Use a mature, resonant, emotionally rich baritone with natural dynamics.
