I (somewhat recently) taught myself how to play the piano solely by playing Mario songs. There's a pretty decent easy piano book which goes through the entire canon.
So the power up sound is a sped-up version of the level end tune? That's cool. I knew Nintendo did a lot of tricky things to make the most out of those cartridges, but for some reason this one strikes me as particularly clever - even more than the cloud/bushes.
Aside: what is that neat flash package used to play and display the notation? For example, when you hover over the "1-up melody" notation, each note plays.
Or the "play slow" feature of the "Jump" music's glissando?
