Subjects will be made to lie supine and relax for ten minutes. EEG electrodes will be applied according to 10-20 system. A baseline EEG (Galileo NT) and ECG in lead II for 10 minutes (Power lab 15 T Labchart by AD instruments) will be recorded. Baseline digital measurement of BP will be done. Saliva for baseline stress markers (cortisol and amylase) will be collected. All the subjects will be instructed to breathe at a rate of 6 breaths per minute, throughout the procedure that will be monitored by the software. After this, a raga from Indian classical music will be played for 10 minutes duration via earplugs connected to the laptop, during which time the recording of ECG and EEG will continue. The time of start of music will be marked using an event marker in the software. Post ten minutes, the music will be stopped and BP will be recorded and saliva will be collected. ECG and EEG recording will continue for another ten minutes to study any residual effects of music on the heart after which BP will be recorded and saliva will be collected again (end of 30 minutes procedure). Stress questionnaire will be administered at the end of the procedure. For those in control group baseline BP, ECG and EEG will be recorded for ten minutes under resting conditions. Saliva will be collected and stored. EEG will be analyzed using Galileo NT software. HRV will be analyzed using the software provided. The saliva samples will be centrifuged at 3000 rpm for 15 minutes and supernatant saliva stored at -20° C until further analysis for cortisol and amylase (ELISA).
