Franco of Cologne was a German music theorist and possibly a composer. He was one of the most influential theorists of the late Medieval era, and was the first to propose an idea which was to transform musical notation permanently: that the duration of any note should be determined by its appearance on the page, and not from context alone. The result was Franconian notation.
