Genius can be defined in a number of ways. One such definition is to be the right person in the right place at the right time; another is to have the capacity to move your audience to tears. Monteverdi meets both these criteria with flying colours. His professed ambition was to "move the passions of the soul," thereby drawing tears from his audience, and he achieved this with greater efficacy than any of his contemporaries. The use of the word "madrigal" on the title pages of his eight collections (and a posthumous Ninth Book from 1651) is therefore deceptive, concealing radical stylistic changes which brilliantly reflect the turbulent, exciting times in which he lived.
