Their voice, however, have no match today, since they had a voice that was superior to normal man and women.
I think people in the XVIII century were musical fanatics, as had such barbaric method to produce high pitch in man.
Most people informed about music know about castration in the barroque era, but this documentary it's quite interesting.
