The melody of Mighty Is The Power Of The Cross by Chris Tomlin runs 279 notes across 96 bars, 4:14 long in G at 138 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.
