The melody of I Wanna Be With You by Mandy Moore runs 367 notes across 54 bars, 4:14 long in Ab at 80 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.
