A quote
Do you not see how many voices there are in a chorus? Yet out of the many only one voice results. In that chorus one voice takes the tenor, another the bass, another the baritone. There are women, too, as well as men, and the flute is mingled with them. In that chorus the voices of the individual singers are hidden; what we hear is the voices of all together.
