The melody of I Won’t Give Up by Jason Mraz runs 378 notes across 81 bars, 3:36 long in E at 75 beats per minute. The tab sits almost entirely in the first two frets, 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.
