The melody of I Don’t Wanna Love Somebody Else by A Great Big World runs 164 notes across 55 bars, 2:34 long in Bb at 128 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.
