Russian pop-rap with prominent live acoustic and electric guitars. The beat should be tight and groove-oriented, with a strong, punchy kick and snare, but the guitars take a leading role in the melody and fills — think of it as a modern, slightly edgy pop-rap where the guitar riffs and solos add character and warmth. Use clean, bright guitar tones in the verses for a grounded feel, and let the electric guitar lead or add distorted accents in the chorus to make it anthemic. Incorporate subtle percussive elements (shakers, light cymbals) to keep the groove alive. The vocal delivery should be conversational and rhythmic in the verses, with a more melodic, expansive sound in the chorus. Mood: celebratory, humorous, and upbeat — perfectly matching the light-hearted, proud tone of your lyrics about becoming a grandfather. Avoid overly electronic or synthetic sounds; keep the foundation organic with the guitars.
