You will need a capo on the 3rd fret for this song.
Anytime you see two dark vertical bars with two dots beside them, that will mean to repeat the area that is surrounding it. In some cases, like the ending of this particular song, you will see a number at the end of the measure. It will tell you how many times to play the entire area surrounding it. In this case, you will play the last measure at the end “6x’s,” which just means six times.
