The melody of O Little Town Of Bethlehem by Traditional Carol runs 140 notes across 17 bars, 1:21 long in Bb at 100 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.
