In the paper, first a short discussion about music therapy is presented. Some important features of the so called modern live style are pointed out in the context of human’s emotional quality. In this meaning of affective states the stimuli art of the daily music influence as a therapy is presented. The main goal of the analysis would be to define, what kind of sounds’ sets should be used, to reach the relaxation state of the human body. It is presented, on the base of spectral analysis of the mechanical sound waves, that music, which is made by mixed (bas, tenor, alt and soprano) chore, seems to be better for these applications, that the one from an typical instrument. There existsound frequencies (proposed in literature) which are much easier attainable for the human voice than for a musical instrument.
