The melody of In The Bedroom Down The Hall by Pasek & Paul runs 444 notes across 113 bars, 5:55 long in Bb at 144 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.
