This version is arranged to play in a standard tuning 
guitar, but each note are correct in order to respect the 
 interludes in order to achieve the technical goals 
onthe instructional video. On a personal basis, I don't 
like to change the tuning on my guitar, because it is my 
only one instrument and I don't like to stress tehe 
neck, truss rod, bolt on union and strings, every time 
that a tab uses a lower tuning.
