The effect of different genres of music and silence on relaxation and anxiety: A randomized controlled trial.

High stress and anxiety in healthy individuals may lead to use different pharmacological and non-pharmacological therapies. The study aimed to investigate the effect of different genres of music on anxiety and relaxation in healthy participants. This study was a randomized controlled trial with a cross-over design. Forty-six healthy undergraduates participated in the study and randomly received different genres of music (Pop, Rock, Western Classical, and Persian Traditional) and silence for five consecutive days between February and June 2018. Each participant was her/his own control. Relaxation and the State Anxiety were checked with Smith Relaxation States Inventory 3 and The State Anxiety Inventory before and after listening to 15 min of music or laying down in silence. None of the five procedures were preferred for a more relaxing effect (P > 0.05). Also, none of the interventions were preferred for reduction of the state anxiety (P > 0.05). Although different genres of music, i.e., Pop, Rock, Western Classical, Persian Traditional, could reduce state anxiety and improve relaxation, they had no extra effect compared to Silence.
