(spoiler) Which instrument hits the hardest?

Which instrument of the Traveler's theme at the campfire during the ending hits you the hardest?

Polls are apparently limited to 6 options so if you're a fan of whatever exact instrument Gabbro is playing (seems like noone can ever agree what it is), please comment.

For me it's definitely Solanum's piano, it just sounds so beautiful and oddly melancholic.
