The melody of So Far Away by David Guetta runs 350 notes across 71 bars, 2:24 long in F#m at 148 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.
