I have to say the Rhythm part for Aerials was pretty fun and easy in general. The first two sections are the hardest part with the E3/OpenA/OpenD, E2/OpenA/OpenD, OpenE/OpenA/OpenD, OpenE/OpenA/OpenD, OpenE/OpenA/OpenD runs. Just keeping the pattern down and then going with the rest.

Pretty easy to play. I need to run through the first two sections a few more times but heck, I think I can play it now outside the game
