The melody of Imagine Me Without You by Jaci Velasquez runs 390 notes across 40 bars, 4:02 long in Ab at 60 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.
