The melody of Touch Of Grey by Grateful Dead runs 381 notes across 75 bars, 4:53 long in Eb at 140 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.
