The melody of Poker Face by Lady Gaga runs 594 notes across 70 bars, 3:39 long in B at 119 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? Poker Face chords and lyrics.
