This is Travis' riff, which runs throughout most of the song. Play over and over and 
every once in a while throw in a little vibrato or bend on some of the notes.

Tuning: Standard

x - mute

note: for the first set of muted notes, I'd recommend using the 6th fret. the rest can 
be on the same as the frets that are played.
