Methods: This research applied pre-experimental design (one group pre-posttest). The sample was 37 female students who were randomly obtained by using a simple random sampling. The data was gathered through a numerical pain rating scale. Then, it was tabulated and analyzed using Paired T-test. Results: The results showed that there was a significant effect with a value of p=0.000 or p <0.05, meaning that the combination therapy of progressive muscle relaxation and classical music can reduce menstrual pain (dysmenorrhea). Conclusions: It is hoped that the combination therapy of progressive muscle relaxation and classical music can be used as an alternative to reduce menstrual pain (dysmenorrhea).
