The melody of The Grudge by Olivia Rodrigo runs 509 notes across 77 bars, 2:36 long in Eb at 128 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 Grudge chords and lyrics.
