This site explores examples of puzzle canon, sometimes stretching back to medieval times but with a bias toward more recent centuries, enabling readers to engage with the music without much specialized historical knowledge.


"Puzzle canon," "riddle canon," "Ratselkanon," "Enigmatic canon," "closed canon," all these terms refer to a sort of canon that is sufficiently strict that a single written melody can represent two or more performed melodies! One of these melodies might be the retrograde of the other, or upside-down, or higher or lower, twice as fast or slow. Only the imagination is the limit. many more possibilities exist. What kinds of clever things have Bach, Mozart and others tried? What other kinds of puzzle canons exist? Who are the unsung heroes of canon from Medieval times to the present? The puzzlecanon website is the place to find out!
