The melody of Slow by Leonard Cohen runs 239 notes across 36 bars, 2:57 long in Gm at 129 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? Slow chords and lyrics.
