The melody of I Need Love by Robin Thicke runs 388 notes across 55 bars, 3:15 long in Gm at 80 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.
Prefer to strum and sing it instead? I Need Love chords and lyrics.
