Pick a 30-second scene from a film, game, or advertisement you know. Describe the emotional intent in 2–3 sentences (what the viewer should feel, why). Then write a prompt for an AI music generation tool specifying: (1) the emotion, (2) three acoustic properties (instrumentation, harmony type, tempo/rhythm character), (3) any constraints (e.g., "no lyrics", "build from sparse to full", "loop-friendly").
