The melody of I Don’t Wanna Know by Mario Winans runs 298 notes across 37 bars, 3:45 long in Bm at 95 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.
