The melody of Flake by Jack Johnson runs 376 notes across 73 bars, 4:13 long in Bb at 92 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? Flake chords and lyrics.
