Pre-Chorus, you dont play this very fast ther are little breaks between each mini riff, but ther not as long as the breaks in the intro mini-riffs(Intro 3rd riff) On the last mini riff it ends in 3 instead of 6, tell me if it would sound better than if it was on the six like the other 2:
e---6------6--------3-----------------------------------------------------------------
B-------------------------------------------------------------------------------------
G--3------3--------5------------------------------------------------------------------
D-------------------------------------------------------------------------------------
A-6------5--------3-------------------------------------------------------------------
E-------------------------------------------------------------------------------------

Chorus, for the chorus i dont know if its too long but u take a look at it. Umm ill just give u the chords and later ull here the strumming pattern. The little picking thing is just a little intro to the other part of the chorus. This is the first riff of the chorus:
e--6----6----6----6-------------------------------------------------------------------
B--4----4----4----4-------------------------------------------------------------------
G--3----3----3----3-------------------------------------------------------------------
D--5----3----5----3-------------------------------------------------------------------
A--6----5----3----5---------5-3-5-----------------------------------------------------
E--3----3----3----6--------6-----6-5-3------------------------------------------------

This is the second riff of the chorus:

Cesar that pratically the whole song. Try to come for something maybe during the picking. But its up to you, so do watever sounds good to you. Im not done with the lyrics so the song might have to change. If u want we can finish the song together. If u do let me know and ill send you wat i have. Ill try to send u a recording but if not well do it over the phone.
