The melody of When The Levee Breaks by Led Zeppelin runs 227 notes across 61 bars, 4:09 long in Bb at 140 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.
