The melody of I Won’t Give Up by Jason Mraz runs 407 notes across 80 bars, 3:13 long in E at 84 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 Won’t Give Up chords and lyrics.
