Music in India has great potential in this study because Indian music is melodic and has somewhat different pitch perception mechanisms. Western classical music which is based on harmonic relation between notes versus the melodic mode (raaga) structures in the Indian Classical Music System (ICM) within the rhythmic cycle music may demand qualitatively different cognitive engagement. The analysis of EEG data to determine the relation between the brain state condition in the presence of ICM and its absence would therefore be an interesting study. How rhythm, pitch, loudness etc. interrelate to influence our appreciation of the emotional content of music might be another important area of study. This might decipher a technique to monitor the course of activation in the time domain in a three-dimensional state space, revealing patterns of global dynamical states of the brain. It might also be interesting to see whether the arousal activities remain after removal of music stimuli.
There are a few unique aspects of raga music which may be considered more therapeutic and recommended for healing. However, there is a scarcity of rational researches in the field, whereas, west music has been researched and has gained pretty much authenticity. But there are various unique elements in raga music or Indian music which can be considered as the medium of more explorations and analysis and further for healing.
