By Cheri-PC This is great. Not only a great warm up, but to have the demo recording of each exercise as a reference point is super valuable.

As another reviewer commented, 'You would think these exercises would be boring. They're not.' That absolutely nails it. Some of the exercises are a variation of Colin's Lip Flexibility exercises (a must have), but Lin has constructed his exercises in such a way that really works the embouchure in a manner I haven't seen in.

I find myself playing the demo between each line I play. The book itself is a great book for so much.flexibility, flow, centering, evenness of sound, etc. And of course having it on my ipad, not having to cart around a bunch of books, and just having it with me when I otherwise might not. Warm ups, lessons etc. I really hope they continue to offer more of these books for ipad. Seriously, this is big. Akash Bangla Tv Serial Datta.
