雨夜的钢琴曲

프롬프트

Create an original 4-minute peaceful instrumental titled "Midnight Rain" for AR Echoes. Slow tempo, approximately 55 BPM. Use delicate felt piano, warm ambient pads, soft sustained strings, and realistic gentle rain falling against a window at midnight. Compose a beautiful, sparse piano melody with long pauses, tender minor-to-major harmonic movement, and soft emotional warmth. Add subtle distant city ambience without traffic horns or voices. Gradually develop the melody, then return to a simple, peaceful phrase. Smooth transitions, spacious reverb, warm tone, consistent low dynamics, and a natural fade-out. Instrumental only: no vocals, humming, speech, drums, percussion, or sudden sounds. Peaceful, reflective, dreamy, and suitable for relaxation and nighttime listening.
