The melody of Light In The Hallway by Pentatonix runs 170 notes across 71 bars, 3:39 long in Cb at 104 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.
