Music Park, called Melody Motorway in the PAL region, is the third course in Flower Cup in Mario Kart 7. The stage consists of musical instruments, such as xylophones, pianos, speakers, and horns. Even Piranha Plants beat their heads to the music in this stage.
Just about everything in the stage goes with the beat, and when driving over the giant piano, sounds of the piano can be heard when driving over the keys. Like every other course in the game, there is an area which is eligible for gliding.
This course is rather similar to Toadette's Music Room from Mario Party DS.
The track made a return in Mario Kart 8 as a course in the Leaf Cup.
