The melody of What You Mean To Me by Gary Barlow runs 258 notes across 56 bars, 2:35 long in Db at 110 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.
