The melody of Breakthrough by Lemonade Mouth (Movie) runs 566 notes across 68 bars, 2:46 long in Db at 112 beats per minute. The tab sits moving up the neck in places, 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? Breakthrough chords and lyrics.
