The melody of Kids Of The Future by Jonas Brothers runs 450 notes across 76 bars, 3:08 long in G at 172 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.
