In 'The Last Emperor,' the quote 'Open the door!' is the desperate cry of a boy-king trapped in his own palace. To capture the intersection of personal tragedy and Chinese history, composer Ryuichi Sakamoto utilized the Erhu. The Erhu is a two-stringed bowed musical instrument, often called the 'Chinese violin.' Its sound is hauntingly human, capable of mimicking a crying voice. Sakamoto combined the Erhu with Western orchestral arrangements to reflect the protagonist's life between two worlds. This score won the Academy Award, proving that the soulful resonance of the Erhu can carry the emotional legacy of a historical movie legend and the heartbreak of his isolated dialogue.
