Women were, by ecclesiastical law, excluded from participation in church music, and as the voices of boys could be used only for a few years, they did not suffice to meet the ever-increasing demands of church music. At first it was attempted to supply the place of the sopranists and contraltists with so-called falsettists. As, however, these substitutes proved insufficient, the soprano and contralto of boys were sought to be preserved in men. And so, in 1625, appeared the first male sopranist in the Papal chapel in Rome. Such sopranists and contraltists soon appeared in great numbers, and as their organs of singing continued soft and tender as those of women, and their compass was the same, to them the education of female voices was given over exclusively. Thenceforth women became the richest ornament of the opera, then blooming into beauty. But only when the ecclesiastical law forbidding women to take part in church music was annulled, did women begin, in the middle of the last century, to take the place of those male sopranists and contraltists. It thus became unnecessary to secure longer duration to the voices of boys, especially as these were never able to attain to the peculiar grace of the female voice, and so this class of singers gradually died out. But still in the first half of the present century there were many of them living and sought for as teachers of singing. _To the disappearance of this kind of singers, Rossini thinks the decline of vocal art is to be mainly ascribed._
