The melody of The Gambler by Kenny Rogers runs 461 notes across 101 bars, 3:05 long in Ab at 176 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? The Gambler chords and lyrics.
