Listen to the record for the time.

Standard Tuning: EBGDAE

Fig.1 starts after some vocal, keyboard, drums and bass only part
but i
think that there's some kind of acoustic riff under the keyboard.

Fig.1
|--------------|-----------|
|--------------|-----------|
|-----------6--|*-6--6--6-*| Repeat x 8
|--7--4--6--6--|*-6--6--6-*| On the last time let the last chord ring.
|--7--4--6--4--|--4--4--4--|
|--5--2--4--4--|--4--4--4--|

When you'll let ring that chord Cristina enters, and under her voice
there's a super heavy chord with the palm muting before the song goes into the chorus.

|----------6--| As before let the chord ring.
