song near li

[Xila]

Im at the body and i found li in it. But i keep hearing a song that sounds like you could sing it. Can someone tell me either:

A:What the notes are.
or/and
B:What it does.

The notes are the same as the Sunken City song. (provided you didn't skip the sunken city via the version 1.0.0 glitch)

The song frees Li, but only after you've recovered 4 spirits to power it up.

Okay, thanks!
