The melody of As Long As You Love Me by Justin Bieber runs 336 notes across 48 bars, 3:11 long in Fm 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.
