The melody of Fat Lip by Sum 41 runs 475 notes across 72 bars, 3:26 long in E at 160 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.
