Version 1: The Eddie Van Halen "Right" Way

The opening chord (as best as I can tell--the bass doubles on the low E string, and
your ear's mileage may vary)

NOTE: This intro chord is plucked in 6/4 time.

D |-7-7-7-7-7-7-|-7-7-7-7-7-7-|-7-7-7-7-7-7-|-7-7-7-7-7-7--|  (total of eight measures)
A |-------------|-------------|-------------|--------------|  drums join final measure
E |-5-5-5-5-5-5-|-5-5-5-5-5-5-|-5-5-5-5-5-5-|-5-5-5-5-5-5--|
