The melody of I Shot The Sheriff by Bob Marley runs 379 notes across 90 bars, 3:29 long in Cm at 184 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.
