If it helps, The pad sounds like Octave C on the bottom with Octave C on the top
Octave C on the bottom drones on and you move a pattern like this on top.
e --c / d--c / and c - c octave again.so on top you play
the 3rd (E) with the Root (C) on top
Then your 2nd (D) with (C) on top
Then your Octave C - C on top
And you move back to 2nd (D) with (C) on top right before the guitar plays.
That will get you close
After the guitar starts in chords for the pad or guitar
