Many other versions of Taurus tab are incorrectly posted on the web with the 
first 4 bars of Stairway to Heaven tab. These 2 songs, based on a commonly 
used A minor descending chromatic walk are vastly different in composition and complexity. 
Only an amateur would confuse them for the same song.
