Music has significant communicative power through both lyrics and beyond words. It tells stories, evokes emotions like laughter, tears and dance, and accompanies important ceremonies. Music reduces pain, increases blood oxygen levels, regulates respiration and heart rate, reduces anxiety and fear, and boosts the immune system. It acts as a natural pain reliever without side effects by distracting the mind and synchronizing brainwave frequencies. Live music is particularly effective as it can respond to patients and transmit vibrations. Different styles of music may be suited to different client needs such as the acutely ill, chronically ill, children/elders, and actively dying.
