The melody of Life Support by Sam Smith runs 261 notes across 22 bars, 2:48 long in G at 60 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.
