This paper explores the ancient healing practice of Five-Tone Therapy within Traditional Chinese Medicine (TCM), a system that links emotions with the function of internal organs and the natural elements. It examines how specific musical tones can be used to restore balance to the body, mind, and spirit by harmonizing emotional imbalances. Drawing from classical texts like the Huangdi Neijing and rooted in seasonal and elemental correspondences, the paper explains how sound is used therapeutically to treat different personality types and emotional patterns. Beyond symptom relief, it highlights how Five-Tone Healing guides individuals toward deeper emotional insight, inner peace, and a more harmonious way of living, showing that healing is not only physical but also a profound journey of self-awareness and transformation.
