Brain Science and Music-Research on Pitch Perception Based on Brain Evoked Potential

Abstract

At the end of the last century, humans’ research in the field of brain science advanced rapidly. Brain science is becoming one of the key science fields researched by different countries. The analysis on neural network of brain is used to research the work mechanism of brain in different tones. In analysis result, the change of brain evoked potential can really reflect the perception of brain to different pitch levels. At different pitch levels, especially for before and after the change, the power spectrum energy density of brain evoked potential signal at different frequency band and the clustering and information absorption of brain’s functional network are obviously different. They are very significant methods of researching music perception at different pitch levels. The two methods complement each other.
