High and low united. Vivaldi often thinks like a child. If his music is played too intricate and grown-up it often doesn’t work, it sounds boring and almost conceited. This music is maybe more of a combination of simple and
intricate. As a magnificat it is a bit special in that Mary hails God for his
choice of her as Jesus’ mother, in a totally desperate, almost catastrophic
manner. Vivaldi’s idea must have been that she had premonitions of what was to come.
