The melody of Gangnam Style by PSY runs 334 notes across 58 bars, 2:21 long in Bm at 130 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? Gangnam Style chords and lyrics.
