I'm surprised this song was never added until now. There are many different ways of playing the guitar part of American Woman. I use a G Diatonic, and this is the easiest set of tabs to play it. It is extremely simple, and shouldn't be difficult to find out how to play on any harmonica key. (GUITAR)--Repeated throughout the song-- 5 6 -6 -6 -6 -6 -6 6 -6 6 -6 5 6 -6 -6 -6 -6 -6 6 -6
