The melody of The Number One Song In Heaven by Sparks runs 445 notes across 99 bars, 6:59 long in Ab at 130 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.
