The melody of Baby Boy by Beyonce runs 714 notes across 72 bars, 3:34 long in Fm at 100 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? Baby Boy chords and lyrics.
