Chords I use are what I think sound good when played on Guitar. Feel free to use any 
sort of fingering or add any extensions to it. For F/A , a normal F can be applied, as well 
as C/E where a normal C can be applied.

Capo on 3rd Fret. Not really compulsory if you don't wanna stick to the original key.
