“Melancholy Piano” is a lyrical soundtrack of pure piano playing, with simple and restrained notes to outline the inner whisper. Between the ups and downs of the keys, the melody is like a slow-flowing deep water-not raging, but every drop carries weight. The left-hand bass area is calm and laid the bottom, and the right-hand melody line winds forward in the middle and high-pitched area, occasionally leaving white space, like a sigh of silence. The whole song is filled with a kind of quiet sadness, not a collapse, not a cry, but the kind of “inexplicable but uncomfortable” emotion when sitting alone at the window one night and thinking of someone or something. It is suitable for use as background music for emotional passages, monologue scenes, flashbacks of memories, parting moments, or any scene that needs to carry “unspoken words” with music. Melancholy, introverted, lingering aftertaste.
