psychological and physiological. However, because the healthful effects of music have not been fully explored scientifically, many questions about the clinical efficacy of music are yet to be answered. In this study the musical selections used were reed flute sound and hard rock music. The information obtained from the present study adds significantly to what is known about the relaxing properties of music, by investigating how exposure to different styles of music the psychophysiological aspects of anxiety. The physiological measure was frontalis electromyography. EMG data taken from individual before music was listened, during listening to reed flute sound and during listening to hard rock music, were examined to extracted power spectral density by welch method which is use to evaluate unstable sign. Power spectral densities of during listening to reed flute and hard rock music were determined differently compared with psd of without music situation. As reed flute sound triggered off the decreased psd value, hard rock music triggered off the increased psd value. There is a reverse ratio between PSD on muscle and relief amount. In conclusion, listening to reed flute music has relaxing property according to hard rock music on frontal muscle. Keywords: Music, Music Therapy Welch Method, Frontalis Eletromyography,
