Dissonance involves a clash—of musical notes, of ideas, of beliefs. Sometimes uncomfortable, sometimes ugly, sometimes simply unpleasant. But, those who listen closely may find value and true beauty in dissonance: the cacophony of two notes juxtaposed with the harmony that follows, two unlike ideas which force us to question our established beliefs. TEDxPurdueU invites you to join us at our virtual event, “Dissonance,” and discover the ways in which dissonance enriches our lives and challenges us.
