At first glance, this appears to be an ordinary minuet, but it is one where Haydn's mischievousness, or rather, his playfulness, is evident. First, try playing only the melody line from measures 1 to 10. Next, similarly play only the melody from measures 11 to 20, but instead of starting from measure 11, play it in reverse, from measure 20, then 19, 18, 17, and so on. You will then discover that it matches the melody from measures 1 to 10.

Similarly, play measures 21 to 32 of the Trio, and then, as before, play measures 33 to 44 in reverse, starting from measure 44, then 43, 42, and so on. You will find that it is the melody from measures 21 to 32. This is a technique called retrograde, and composers like Bach also wrote such puzzle-like pieces. Therefore, with a playful spirit, wondering how many people will notice it, try playing it lightly and enjoyably.
