When I played mallet percussion back in high school, I played Flight of the Bumble Bee on our Xylophone for a regional competition and won a second place finish. It was a tricky piece of music to play and took a lot of hand-key coordination.

View examples such as Alla Turca or the classic Chopsticks, or punch in your own MIDI-formatted song for a taste of the distribution ivories.
Here’s the distribution for everyone’s favorite, Chopsticks.
