Results: The control group showed the increased value of anxiety level of0.8 without music intervention (t= - 1503, df = 24, p<.05), whereas the intervention group showed the decreased value of anxiety level of -5.52 (t=5.081, df=24, p<.05). Meanwhile the independent t-test results for both groups showed a significant difference between group (t= 3,373, df=48, p<.05). Conclusion: Music therapy has significant effect in reducing preoperative anxiety levels of patients. Keywords: anxiety, preoperative, music therapy
