YouTuber Walking Bass Piano Man is a master of the jazz piano, as demonstrated by numerous jazz renditions of popular songs, including the works of Bon Jovi, Ben E. King, and Ludwig van Beethoven.
In this video, they take the iconic opening theme to Sesame Street and play it over and over again, incrementally jazzing it up. Starting at level 1, it's not that different from what you'd see on television. But by the time that Walking Bass Piano Man gets to level 8, it's a jumping melody that flies across the keyboard faster than it seems two hands can manage.
