The melody of Welcome To The Jungle by Guns N' Roses runs 364 notes across 39 bars, 4:02 long in G at 126 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.
