The guitar gods must have found pity on me, because the I came stumbled across this workout in an Oct 2007 edition of Guitar World Magazine just  a few days ago.  What are the odds of that happeniing out in the deserts of Qatar ... really! Anyway, he outlines a practice regime where you're developing a technical base, picking skills,a familiarity with the fret board and over time, speed.  It's great for a newbie such as myself because it structures your time with a bit of everyhting you need, technically speaking of course. 

He would spend the first hour doing the technical exercises, the second to scales and the third to chord work.  He would repeat each of them three times then the remaining time he would spend the remaining time trying to reproduce spoken phrases as passages on the guitar.  Here's why I enjoy this workout.  He divides the exercises into three catagories: linear picking, angluar and stretching.  He'd follow that up with a three hour chord study, playing the major scale in all 12 keys, practicing the scales in interval patterns.

I know many of us don't have ten hours to deveot to practice, but if you scale down the times to fit your schedule I think it could be benefitial.

This thing is vast!  I couldn't begin to explain it all here, but i thought I'd share it with you all.  I'm sure you can find it somewhere on the internet.  Enjoy!

Thanks for posting Vai's great practice schedule....now if i could only get myself to spend that kind of time each day plus covering all those topics... ! ! Hope you're stayin' good over there. Anything you need, let us know.

Cheers,
