Speaking about chords? Mmmmm!
The thing with this intro is the pedal A note. So you can play it in two ways (on the guitar):
| A Bm/A | G | So the Bm chord with the A bass
Or you can play A on 5 fret of the 1st string on all the chords:
| A Bm7/A | G9 | But it is not very comfortable thing to play on the guitar...
On the guitar you can play the melody like this:
5 5 5 3 7
2 3 0 3 0
2 4 0 0 0
But on the keyboard it sounds very different, this is the typical piano lick. Try to play the melody with harmony ( AC# - BD - GB - etc... ) while playing the A pedal. Or play with the pedal A bass.
SO! I said many words, but with little info for keyboard players. The main thing is the melody!
Top melody is:
A---- A---- A!------- G-- B-- A---- B---- G-- ------
Bottom melody is:
A---- B---- G-------- G-- G!- A---- B---- G--------
Play both at the same time, add chords with pedal bass and yo'll get the result.
