Capo 7th fret

Standard (EADGBE)

Thats the chord progression throughout the song, and the Em is played 2/4 of the time

the same rythm... So if you played the Em 4 times you play the D in the same pace but only

and then the C in the same pace but only twice, as said, watch to the video to understand.

Listen to the song for strum rythm :)
