While there’s no shortage of ways to distract yourself while playing Final Fantasy 7 Rebirth, one of the most unexpected minigames is the surprisingly deep piano system. In most of the major hub towns you encounter across the expansive world, Cloud can find a piano to sit down at and tickle the keys. You’re free to play any song you want in free play, but you can turn this system into a full-on rhythm game, almost like Guitar Hero, by collecting sheet music of some of the game’s most iconic tracks. There’s even an NPC near each piano who will reward you if you get a high enough rank on each song. Cloud may not be the most expressive in his words, but he can sure play the piano with heart. Here is where you can find all the sheet music and what rewards await if you can master them.
