In order to keep their music akin to nature, it was necessary to give liberty to the singer and player to sing and play as he wished. Naturally, uniformity was lacking, and a standardized system could not be made. That is why this music a ways remained an individualistic art only - not an education. For this reason the music of the ancient people had its advantages and a great many disadvantages. The advantages were this: a musician - a singer or player - was never bound to sing in a particular way in order to execute properly the music he wanted to play before the public, but was always free to give the music according to his inspiration at the time. It gave him full liberty to express his emotions, his passions, without any outward restrictions which he should obey. When there were a number of singers or players, no doubt it was then necessary to set a certain standard - yet that standard did not restrict them very much. It is this order which was called music.
