The melody of Too Much For One Heart (from ‘Miss Saigon’) by Boublil and Schonberg runs 256 notes across 78 bars, 3:49 long in Ab at 48 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.
