The melody of Don’t Know Why by Norah Jones runs 170 notes across 31 bars, 2:38 long in Eb at 88 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.
