The melody of With You by Chris Brown runs 624 notes across 76 bars, 3:35 long in Ab at 85 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.
