Fortnite’s most complicated Boogie Down mission sends players to visit an oversized piano, and in the Prestige version play the sheet music while they’re there.
The piano in question is located on the furthest east edge of the island. You can see the location marked on the map below.

All you need to do to complete the basic version of this challenge is land at the piano, but the Prestige version is a little more complicated. Next to the piano is a small sign with a piece of sheet music. This challenge asks you to play the music that’s on the sign.
Thankfully, if you aren’t sure how to read music, or which keys on a piano are which notes, everything in this challenge is labeled for you. Just play the notes C-E-G-E-C in that order to complete the Prestige mission.
Each key on the piano is marked with its note, but the notes themselves aren’t next to each other. You’ll need to make sure that you don’t hit any other notes in between the ones you need for this mission or it won’t complete properly.
