This sounds about right to me.
Standard tuning. EADGBe
e|---------------------------------------------------| B|-----1---------------------------------------------|G|-------2--------3----------------------------------| D|---2----------3---3--------------------------------| A|-0---------1----------3-/-5-/-9--------------------| E|---------------------------------3-----------------|
Listen for strumming pattern. Waltz style.
e|----------1----------------------------------------|B|----------0----------------------------------------|G|-1-----1--0----------------------------------------|D|-2--3--0--0----------------------------------------|A|-2--3--2--2----------------------------------------|E|-0--1--3--3----------------------------------------|
Very simple and very good. Such an awesome and meaningful song.
Enjoy.
