3DS Music Park

Music Park (known as Melody Motorway in the British English version) is the third course of the Flower Cup in Mario Kart 7. The course takes place on a winding circuit floating in space, containing several musical instruments, including a giant xylophone and piano, as well as giant tambourines that act like Mushroom Trampolines. All instruments make their own sounds when driven over or passed by. The course reappears in Mario Kart 8 and Mario Kart 8 Deluxe as the third race of the Leaf Cup.

Course layout
The course starts off with a road, with trumpets and a large violin visible. Following this is a prolonged turn around a set of piano keys (with the black keys being trickable, then a straightaway with two Big Piranha Plants planted. The Piranha Plants are surrounded by circles of light, signaling the range in which they will bite racers, causing them to spin out. The Piranha Plants swap sides every lap. After this is a slight turn with a small shortcut ramp off to the side near a Note Block. After marimba and vibraphone themed turns (which have raised trickable ramps like the piano), the tambourine appears, acting like a Mushroom Platform. In this section of the track, the walls are adorned with musical staffs.

This section is followed by a split ramp (two ramps that each alternate between being a regular ramp and a Glide Ramp) that leads to an area containing Bouncing Notes, which jump up and down. Three metronome beats are played just before they hit the ground. In Mario Kart 7, after 1 minute and 52 seconds have passed, they start to jump right after they land. Any players that race beneath a Bouncing Note when it lands will be flattened and spin out. However, if players are near one of the notes when it hits the ground, they will be launched into the air and can take advantage of the air time with a trick boost, signaled by the flashing of the floor. Following this section is a big turn with a smaller tambourine trampoline nestled within, which can be used to cut the turn. The tambourine can be combined with an off-road shortcut within the left turn leading to the finish line.

The banners around the course have the name "Music Park" on them, even in regions where the course's name is or is derived from "Melody Motorway".

Mario Kart 8 / Mario Kart 8 Deluxe
Music Park makes its classic course debut in Mario Kart 8 and Mario Kart 8 Deluxe as the third course of the Leaf Cup. There are no changes made to the track layout, but there are several cosmetic changes. The course banner now resembles a guitar neck with strings, and the Mario Kart logo is now multi-colored. The Bouncing Notes now squint when they land, and them speeding up is no longer based on a timer. This time, they do not speed up until the player in 1st place begins the third lap, and they stay on-beat with the new, faster tempo. In the area they are in, the metronome played is louder than before. A few additional coins have also been placed around the track. Small Bouncing Notes have been added at the start/finish line, jumping in time with the music.

Mario Kart 8 Original Soundtrack liner notes
"This is a special version we've come up with for the soundtrack, with some additional sound effects that you hear while going around the track."

Trivia

 * The track layout bears a striking resemblance to Silence 2 - Wavy Road from F-Zero X.
