The melody of O Come, O Come, Emmanuel by David Crowder Band runs 266 notes across 48 bars, 4:12 long in E at 65 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.
