The melody of When I Think About Angels by Jamie O'Neal runs 436 notes across 78 bars, 4:47 long in Bb at 120 beats per minute. The tab sits moving up the neck in places, 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.
