The melody of Poker Face by Lady Gaga runs 492 notes across 50 bars, 3:21 long in Am at 120 beats per minute. The tab sits low on the neck, mostly under the fourth fret, 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.
