The melody of My Prerogative by Britney Spears runs 418 notes across 70 bars, 3:32 long in Ebm at 110 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? My Prerogative chords and lyrics.
