What a beautiful song by Phoebe, Julien and Lucy, and it sounds amazing in your voice. I was thinking of doing a cover too. Listening to yours has motivated me to do it definitely! Besides that tunning you're playing fits perfectly for my voice too.
it's open c and im just using the top two strings-- the verses just switch between open c, f (5th fret), and g (7th fret). then in the chorus there's an Am which is 9th fret
