heres the intro to the song which is on a ukelele but it sounds alot cooler like this.
it's just C, Em, Am over b, and then B.it's another way to play it for tabs it's:
[ Tab from: https://www.guitartabs.cc/tabs/j/jack_johnson/breakdown_tab_ver_2.html ]
----0----------0------------0-------------3----------------------------|
---1--1------0---0--------1---0---------3---3--------------------------|
--0----0---0-------0----2-------0-----0-------0------------------------|
-----------------------------------------------------------------------|
3--------2------------0-------------2----------------------------------|
-----------------------------------------------------------------------|
C Em Am/b B
YOu just repeat these two cords to complete the second guitar part in the intro also
have fun
