Hi guys

I've been playing for over 10 years so not exactly a newbie but I'm not "there enough" to tab the songs myself.

Looking for help on this relatively new original acoustic by Nathan Hartono. Its one of the soundtracks on a HBO miniseries. I suspect he tuned his guitar differently as I can't get the same result.

Any help much appreciated. Thank you
