If Beethoven Wrote Variations on Children's Tunes

A few days ago I came across this incredible impression of the familiar tune “Old MacDonald Had A Farm” played à la Beethoven by Polish-Canadian pianist Daniel Vnukowski, and it's so good I simply must share it. I've listened to enough Beethoven over the years—he's one of my favorite composers—to tell that this is absolutely spot-on:

Variations, or variational forms, were a great favorite of Beethoven's judging by the number of them he wrote, though he didn't publish many of them suggesting it was something he did for fun. The Diabelli Variations are probably his most famous among the ones he did publish, though I especially love the Eroica [Heroic] Variations, both the version for single piano and how they reappear in the final movement of his third symphony, the ‘Eroica.’ Anyway, apologies if this song gets stuck in your head as it has mine, but there are certainly worse pieces of music to have that happen with. A hui hou!
