[Intro: deep heartbeat-inspired electronic beat, steady hypnotic pulse, dark spacious atmosphere, bass locked tightly to the beat, no vocals] [Main Theme: same heartbeat groove as the original song, deep rounded kick with a distinct secondary pulse, warm analog synth bass, sparse dark analog synth motif, wide stereo atmosphere] [Development: keep the exact heartbeat groove constant, gradually introduce additional analog synth textures, subtle low percussion and distant electronic accents, melodic movement above the unchanged pulse] [Instrumental Break: heartbeat groove continues alone with deep bass and a minimal analog synth phrase, spacious and hypnotic] [Expansion: stronger analog synth layers, wider stereo field, deeper bass, subtle textural percussion, heartbeat groove remains the central rhythmic identity, no change to the pulse] [Climax: full atmospheric analog synth arrangement around the original heartbeat beat, powerful low end, wide cinematic textures, hypnotic repetition, intensity through density and space rather than speed] [Breakdown: remove layers one by one, heartbeat beat and bass remain] [Outro: original heartbeat groove gradually stripped to bass and pulse, final beat dissolves into silence]
