Abstract
From the view-point of "autonomische Musikasthetik", the ethos-theory of ancient Greek is not always right. But it seems that the aesthetical value of music has any kind of relation to the ethical value particularly in the "polis" of ancient Greek. For the consideration of this problem, it is not enough to reflect upon the correlation between work, sound and musician. Moreover we must think over the audience. Thus we can make clear the ethos-problem not only aesthetically but also sociologically. We should like to contemplate this essential problem by finding out the ancient Grecian music as an ideal image.
