Abstract: “Effect of music on autonomic nervous system (ANS) from Heart rate variability (HRV) signals of pre-music and on-music states is a very recent area of research. ‘n-bit’ rank, for some fixed n, of symbolic dynamics has already been applied in connection with HRV signals of Healthy and CHF subjects. But such a study is completely new in connection with effect of music on ANS through HRV signals. The present paper considers 4-bit rank of symbolic dynamics of HRV signals in both pre-music and on-music stages. It shows that the effect of Music is significant in the on-music state. Moreover it also proves that the significant effect of music is not same for all the subjects.”
