Our study demonstrates the enhancement of task performance aided by music. Task performance and associated physiological changes were studied in participants who listened to music (Indian classical instrument or Indo jazz). Their mood and their perceived emotions were evaluated using positive and negative affect schedule and self assessment manikin scales, and their pulse rate was measured. Visual Go and No-go trials were given as task stimuli and task performance was measured. Changes in the mean pulse rate were significantly low (P < 0.05) during Indo jazz. We conclude that Indian classical instrument and Indo jazz induced positive effects and enhanced task performance.
