I asked a friend to show me how to play "Dia Mau" from "Ornatos Violeta", since there 
any tab for it, and Ornatos is one of the best portuguese bands ever in my opinion.I 
to tab it and here it is:

INTRO
Guitar:

e|-------------------------------------|
B|-------------------------------------|
G|-7-7-7-77----------8-8-8-88----------|
D|-7-7-7-77-8-8-8-88-8-8-8-88-7-7-7-77-|
A|-5-5-5-55-8-8-8-88-6-6-6-66-7-7-7-77-|
E|----------6-6-6-66----------5-5-5-55-|

You'll easily get the strumming pattern if you hear the song itself.

e|-------------------------------------|
B|-------------------------------------|
G|---------6------------6--------------|
D|-------6---6---4----6---6---4-2------|
A|-----4-------4----4-------4----------|
E|-------------------------------------|
