lol. this is extremely easy since i sounded it out in less time then the song took to get over.
i'd say they play in standard tuning EADGBE
First E being the 6th string and the Last E being 1st.
on the 4th string or (D) place your finger on the 17th fret with another finger on 3rd string or (G) on the 12th fret. Play with song to get rhythm its fairly easy. After this you will slide your fingers up the neck 16th fret and 11th fret, then 14th and 12th to 12th and 12th. Use the D and G strings.
That should be the chords used? lol.
