The melody of The Rest Of Our Life by Tim McGraw feat. Faith Hill runs 352 notes across 83 bars, 3:39 long in D at 120 beats per minute. The tab sits almost entirely in the first two frets, one note at a time — no chords to barre and no strumming pattern to keep up with. A piano backing track plays the chords and bass underneath, so the line you are learning sounds like the record even at half speed.
