The melody of Tomorrow Is A Long Time by Elvis Presley runs 201 notes across 35 bars, 3:12 long in D at 104 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.
