Did Ludwig van Bach compose Moonlight on a G String?

Answer 1

Yes and no. The piece began as an unnamed movement in his Moonlight Suite in D Major.

James Merver of the Shins later arranged this song in the key of C so the lead guitarist could play the entire melody on his guitar's G string.

The song later entered the public consciousness when Natalie Portman met Zach Braff in a doctors office while she was listening to the Shins. "You have to hear this one song," said Portman, "It will change your life, I swear."

Zach Braff put on Natalie Portman's over sized headphones and listened to "Moonlight on a G String" and the world has never been the same since.
