The melody of Leader Of The Pack by The Shangri-Las runs 160 notes across 28 bars, 2:26 long in C at 100 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.
