Dimostrationi harmoniche Gioseffo Zarlino, 1571-1590 Dimostrationi harmoniche Venice, 1571 Folio IC55 Za189 571d Zarlino was among the most significant successors to Gaffurius, a speculative and practical theorist of harmony and counterpoint. The Dimostrationi harmoniche followed his influential Istituzioni harmoniche, published in Venice in 1558. With both works, he wrestled with concepts of modality and consonance and laid the groundwork for a codification of the rules of counterpoint.
