           *       *    *play those notes as eigth notes


The chords come in for a portion of the chorus each time.

     Emaj  Emaj13(no 3rd or 7th) Emaj13 (no 7th or 9th)
a light strumming pattern is all you need, but the last time he plays it in each chorus 
only plays the third chord once and then says "keeps us locked in here."
