The melody of Not In That Way by Sam Smith runs 158 notes across 46 bars, 2:15 long in Bm at 68 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.
