The melody of The Most Wonderful Day Of The Year by Glee Cast runs 211 notes across 97 bars, 2:39 long in Ab at 120 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.
