The melody of For Whom The Bell Tolls by Bee Gees runs 392 notes across 37 bars, 2:49 long in E at 100 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.
