The melody of It’s Christmas Time All Over The World by Hugh Martin runs 320 notes across 85 bars, 3:10 long in Ab at 240 beats per minute. The tab sits almost entirely in the first two frets, 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.
