In this article, we study the effect of music on human body and mind. As a parameter for measurement of the physiological condition we choose the heart rate variability signals taken from subjects listening to a particular type of music, which is Rabindra Sangeet (love chapter) in our case. The subjects are allowed to listen to the music for a fixed time span and then we take easements of HRV signals with our own ECG machine. For data analysis the Poincaré plot in spherical coordinate is used. Each of the plots obtained from second order differences form a single cluster looking almost like an ellipse having some outliers. We observe that the volume of the cluster is reduced remarkably in the data of the on music state as compared to the data of pre music state; further the amount of reduction is not the same for all the subjects. This proves that music has some definite common effect on human physiology. Our study shows that this particular type of music gives a complete different physiology. This can possibly be used as a tool to deal with different medical problems such as stress management or hypertension.
