Here we see the first half of the song, as played by the main rhythm acoustic guitar. There are 2 guitars in the song, acoustic and electric. You can hear both in this ActionTab (they don't play exactly the same thing). This acoustic part is the easiest of the 2 guitars. If you are interested in the electric guitar part instead - click here.
The song revolves around just 4 chords. The song begins by strumming through these 4 chords just one time each. The chords are:
E5 - You can remove the little finger and just play the normal E minor chord instead if you prefer. The little finger here transforms the chord from E minor to a very full E5 chord.
D5 - A standard D powerchord in open position.
G major - The full chord. You can use your little finger instead of 3rd finger on the high G note if you find it easier.
A major - Just a typical A major chord.
After the Intro the strumming picks up more, but the same 4 chord cycle remains throughout the entire first half of the song!
At certain points (the pre-choruses) the same chords are strummed a little more energetically:
E5 - D5 - G major - A major
