For musicians, performance problems often go unnoticed at first and have several different starting points. Regardless of the starting point, the “problem” manifests physiologically as tension. It is useful for therapists, doctors, and other specialists to see clients perform. Corrections need to be made to their physical, mental, and emotional approach to performance. Retraining with surface electromyography biofeedback and video helps identify elevations in muscle tension and incorrect body alignment. Feedback-assisted retraining helps to bring about self-awareness and the skills to reduce tension and achieve optimal performance.
