Query: Applying these exercises really makes a difference!

As a vocalist, using these exercises has helped me immensely already (after only just finishing the 6th lesson!) This is my second time around with them, (did six years ago to help develop diaphram). I'm going to practice regularly so as not to get "rusty" again. Wish I could get in hardcover. . .
