The melody of A Holly Jolly Christmas by Lady A runs 167 notes across 50 bars, 1:57 long in Db at 150 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.
