Sound healing therapy uses aspects of music to improve physical and emotional health and well-being.
Healing with sound is believed to date back to ancient Greece, when music was used in an attempt to cure mental disorders. Throughout history, music has been used to boost morale in military troops, help people work faster and more productively, and even ward off evil spirits by chanting.
Music therapy can reduce stress and promote relaxation. It’s been shown to be more effective than prescription drugs in reducing anxiety levels before surgery.
Music therapy is used to treat symptoms of a number of conditions, including:

anxiety disorders
depression
post-traumatic stress disorder
dementia
autism spectrum disorder and learning difficulties
behavioral and psychiatric disorders
cancer
Some of the supposed benefits of music therapy include:

lowers stress
decreases mood swings
lowers blood pressure
lowers cholesterol levels
teaches pain management
lowers risk for coronary artery disease and stroke
improves sleep
Music therapy uses different aspects of sound to improve your emotional and physical well-being. How it works depends on the method being used.
A session may involve sitting or lying down while listening to music or sounds from a speaker or instruments, or having vibrations applied using a special tool, such as a tuning fork. Depending on the method, you may be encouraged to participate by singing, moving, or even using a musical instrument, or you may need to remain still and quiet to let the sounds take effect.
Though evidence may be limited on some methods, music therapy has been found to be effective for stress reduction and relaxation and has been shown to offer many health benefits.

There is little risk to listening to music. Find the sounds that work for you.
