Here's the lead riff for All My Fountains by Chris Tomlin, off the Passion: Here For You album. 

To start off, you play both the 5th fret B string and the open high E string, 
so it makes a droning sound, just like when you tune. 
You play both the B and the high E string the entire time. 
Comment or message me if you have any questions. Enjoy!
