According to Osho, the difference is that real music arises from a silent, meditative mind and dissolves the ego into pure listening, bringing relaxation and even healing; the 'gymnastics' of music is mere madness—ego-driven display and emotional discharge masquerading as art, exciting the body, seeking applause, and deceiving the performer and audience alike.
Real music comes from inner silence and calms you; flashy, showy music is just ego and restlessness pretending to be art.
