The melody of Rather Be by Clean Bandit feat. Jess Glynne runs 385 notes across 46 bars, 3:32 long in Am at 112 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.
