This is a simple arrangement that uses the same chord positions as the fingerpicking arrangements that follow. It probably sounds best if you just strum each chord slowly with your thumb. Be sure to only play the strings designated in the tablature. Since the melody is on the 2nd string at times, when you play those chords you should omit the 1st string so the higher note on the 1st string doesn’t drown out the melody.

The recording below is of the more advanced fingerstyle arrangement.
