.if there is one aspect of this program that sort of slips thru the cracks when it comes to importance..at least to me..it is the instruction to, in tandem with the concert hall breath,’mimic or copy the feeling of the of the Singing C’. When I really take that message to heart and apply it to my playing, the results are really quite staggering and all the actual exercises with notes just improve and become easier almost instantly…I constantly go back and watch the videos and I continue to improve and better understand the concepts..very cool..Jim
