Sound has been used in many cultures to change and move energies. For example, Mayan balls can clear an aura. When shaken next to a part of the body where energy is blocked, the balls do not sound, but continue to shake the balls and it moves the energy. Chinese balls also can move energy within the body. Temple bells are used to encourage the focus of energies on spiritual matters.
Music can heal, but remember, many illnesses bring a message of spiritual growth.
Once that has been accepted and understood. All the various music instruments affect us differently. For example, drums, gongs, tambourines, and triangle, affect the lower chakras and the physical body. In the past, soldiers marched to war behind beating drums. The noise of the drums gave them courage.
