The melody of Light It Up by Major Lazer runs 421 notes across 55 bars, 2:46 long in Am at 106 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.
