The melody of Jailhouse Rock by Elvis Presley runs 143 notes across 17 bars, 0:51 long in Bb at 160 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.
