The melody of A Hard Day’s Night by The Beatles runs 258 notes across 46 bars, 2:10 long in G at 138 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.
Prefer to strum and sing it instead? A Hard Day’s Night chords and lyrics.
