The melody of Don’t Worry, Be Happy by Bobby McFerrin runs 94 notes across 14 bars, 2:47 long in C at 138 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.
