Listen to Jinora's Light from Book 2 Soundtrack
The Avatar series as a whole is known for its outstanding soundtrack composition. It is one of the key factors that allows Avatar and Legend of Korra to stand out from many other television shows. The masterminds behind the music you hear is Jeremy Zuckerman, the main composer of the music.

He was kind enough to share a piece from the Legend of Korra Book 2 soundtrack, titled Jinora's Light. You can listen to it below.
