The melody of Saturday Sun by Vance Joy runs 448 notes across 102 bars, 3:17 long in Db at 190 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? Saturday Sun chords and lyrics.
