This whole part is being plucked. Use your thumb to pluck the bass notes and your middle index finger to pluck the higher notes. e --------------------6---6---6---6---------------------------| B ---5---5---5---5----6---6---6---6---5---5---5---5---3---3---| G ---5---5---5---5--------------------5---5---5---5---3---3---| D ------------------------------------------------------------| x2 A ------------------5---5---5---5---3---3---3---3---2---2-----| E -5---5---5---5----------------------------------------------| Note: Nick Jonas, the person who normally plays this part of the song, usually bars the fret to do the first few notes. I personally find that harder. Whatever works for you is though.
