Methods and materials: The effect of at least 3 different Indian classical music ragas on the autonomic functions and brain waves of subjects will be studied. Healthy subjects will be recruited from M S Ramaiah Instituitions. Selection bias will be avoided by randomization using computer generated random numbers. All numbers generated will be kept in an opaque and sealed envelope. The envelope will be opened by the research assistant after the baseline assessment of each participant and assigned to each of the seven groups randomly, into all intervention and control categories. Each group will randomly be assigned to listen to a particular raga using block randomization. The control group, the seventh group, will not receive any raga, but HRV,BP, EEG and saliva will be recorded and collected. Literature given in Gandharva veda and raga chikitsa will be used to choose ragas which have varied health benefits especially on the cardiovascular system. The ragas which have been said to normalize the BP are ahir bhairav, bhimpalas, hindol, puriya, kausikanada and todi. Ahir Bhairav, Kausi Kanada & Bhimpalas will be used for the present study. Detailed methodology: The investigators will include a few questions inquiring the subjects' preference of type of music, previous experience with music instrumental or vocal training and note the same. A general health check up will be done for all subjects. The BMI, waist hip ratio and BP in sitting position measured twice after five minutes rest (Sphygmomanometry) in between will be noted. A stress questionnaire (State Trait Anxiety Inventory) will be administered prior to and after intervention to assess the baseline level of stress and the change in stress levels after music intervention.
