The melody of Smile Like You Mean It by The Killers runs 181 notes across 38 bars, 3:50 long in F# at 124 beats per minute. The tab sits low on the neck, mostly under the fourth fret, 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.
