Claim: Gerard Kockelmans, influenced and inspired by twelve-tone music, was a master of counterpoint, which is defined as the relationship between two or more musical lines (or voices) which are harmonically interdependent yet independent in rhythm and melodic contour.
Evidence: Although he was clearly influenced and inspired by the twelve-tone music, which was very popular in his day, he never completely embraced this style. He was a master of counterpoint. In music, counterpoint is the relationship between two or more musical lines (or voices) which are harmonically interdependent yet independent in rhythm and melodic contour.
