Hi Bruce,
Sorry, never seen/heard Portnoys study stuff. Brilliant player though.
I learnt a lot from this book
http://www.melbay.com/product-print.asp ... D=95452BCDIts one of David Barrats earlier books with cd.
Depends what level your looking at . The above book deals with tongue blocking, bends and riffs. I would say intermediate.
He has got an online school now that looks good. Got a couple of freebie lesson too, so you can check it out, before paying. Deals with advanced intermediate stuff like solo building.
http://www.bluesharmonica.com/homeI haven't signed up, just had a look at the free stuff out of curiosity.
I was in a rut, regarding most of my playing and decided to take it all back to basics and try and play more simply, and melodic.
Attempting to start my solo's simply, then build and build, always mindful of the melody. Trying to go somewhere with it rather than just noodling.
Its not easy !
Failing that go and see Stevie Weston !!!
Good luck
Cameron
