The melody of I’m Gonna Sit Right Down And Write Myself A Letter by Paul McCartney runs 135 notes across 41 bars, 2:12 long in Eb at 125 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.
