The melody of Pretty Amazing Grace by Neil Diamond runs 399 notes across 79 bars, 4:40 long in Bm at 136 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.
