Positive and therapeutic effects of music on living beings are known for centuries. The ancient Greeks and Assyrians used music for healing and achieving one's maximum potential. Today it is known that a cat purring vibration sound reduces pain, accelerates bone growth, strengthens muscles and heals wounds. Mozart effect refers to a short-term increase in spatial skills after listening to the Mozart's sonata for two pianos. Most scientists all around the world believe that such a result is dependent on the level of excitement, intensity of evoked emotion and motivation, rather than a direct influence of music on the neural circuits in the brain. Also, some emphasize the importance of music education in the continuance of the effect of music on the listener. Certain types of music evidently reduce stress (lower levels of cortisol) as well as the number of heart attacks, increase brain function (probably by buildig up a new interconnections and stimulating interactions between the ear and the brain, but also between different structures within the brain) and help in cases of many diseases (Alzheimer's disease, ataxia, multiple sclerosis, depression, ADHD, etc.). That is why growing scientific researches point out the significance and universality of music in everyday life. The purpose of this study is to understand how the music is processed and interpreted in the brain, to explain the way by which sound (as a combination of tones) improves one's perfomances and capacity, and specify the use of music in different areas of human activities.
