Despite being gifted with wisdom, there are things he knows he won’t remember if he doesn’t write them down. (He’s the greatest proof that one can be wise without being intelligent, but he’d rather keep that a secret.)
So he composes a series of ditties without song; short nuggets of good things to hear and nod at whenever it should catch someone’s fancy. Perhaps one day, they’ll be overused and overheard, and thus lose their meaning, even to the most diligent of scholars. But for now, he writes them down, and hopes they’ll be useful even when he’s long lost his wisdom to time.
