The melody of I Want You Back by The Jackson 5 runs 313 notes across 35 bars, 2:20 long in Db at 92 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.
