《月色下的誓言：Cinematic Version》純鋼琴獨奏

Solo grand piano, intimate concert hall recording, 6-7 minutes. Romantic minor key waltz in 3/4, around 66 BPM. Expressive rubato, natural pedal resonance, subtle mechanical key noise. Left hand broken arpeggios evolving into wider octave textures. Right hand lyrical singing melody with occasional double-note harmonization. Emotional restraint over sentimentality. No orchestration, no background layers. Dynamics shaped by breathing phrases rather than fixed tempo grid. Ending with suspended minor add9 chord, long natural decay.
