The melody of Walk Away by High School Musical 3 Cast runs 417 notes across 53 bars, 3:33 long in Ab at 96 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.
