The melody of I Am The Walrus by The Beatles runs 289 notes across 39 bars, 3:22 long in A at 80 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.
