To get a piano, you must get vending machine coins. You can find these on various story islands. Then, go to Tangaroa city (If you need help, see my guide on story islands). In front of the main building, there will be multiple vending machines. One will have a piano option. Dispense it, collect it, and bring it back to your raft where you can place it.

To play the piano, you can use the number keys on you keyboard.

If you hold shift while playing a note, it can become a lower version of the note. Hold space while playing a note, and it will be a higher version.

While reading the notes to play this song, you may notice some notes in brackets. These act as a kind of code to make the notes easier to understand. When a note is in brackets and has an SH before it, that means you must press shift with it. If it has an SP before the note, then it is held with space.

Here's how to play it:

0, 0, 0, 8, 0, [SH5], 5
