Abstract

Abstract : Introduction . Music, though used predominantly as an entertainer, studies have shown that music has a significant effect on the body and the mind. But, most of the scientific evidences are now being created for western music (Mozart, Beethoven etc.). Unfortunately, evidence regarding the health benefits of Indian music is extremely meagre. In this study the effect of Indian music on health with special reference to electrophysiological parameters was evaluated. Sama Veda enlists the various scales (ragas) and their health benefits. Objective: To evaluate the effect of 3 select Indian classical ragas on stress markers and brain via electroencephalogram (EEG). Methods . In this triple blind study, 140 subjects aged 18-30 years were randomly divided into 3 groups (A, B, C, D; 35 in each group). The first 3 groups, received music intervention (3 ragas), while the group D served as control. Stress was measured before and after intervention using State Trait Anxiety Inventory (STAI). EEG (19 channel, Galileo NT) was recorded before, during and after music (each condition 10 min). Analysis of data was done using SPSS and BESS Software (Axxonet System Technologies Pvt. Ltd.) and MATLAB software (Mathworks). Results . The 3 groups were comparable. Stress reduced with all 3 ragas. Between conditions effects in theta, alpha, beta and gamma bands were observed which got restricted to only alpha band at right frontal region after collapsing the conditions. First 2 minutes data revealed predominant effects on raga A on theta, alpha, beta, gamma power; raga B on alpha, beta gamma power and raga C showed a significant difference all 5 wave power of EEG. Conclusion . Music reduced stress. It is the scale presented as a whole, as it unfolds, that affected the EEG. The significant hemispheric differences with each raga, particularly, frontal asymmetry is in line with the model of hemispheric specialization concerning perceived positive or negative emotions proposed by Heilman.
