Responding to an old post...
I just signed up yesterday for AW with Christine Peery and am extremely pleased. I like the structure and clarity, and I think the first practice instruction (a deliberate and specific "strike" to the keys) has already improved the playing I had developed from a month of Skype lessons with someone else. The method reminds me of Montessori a little bit. Ordinarily that might not be a compliment :-).
In addition to the structured approach, I like the "asynchronous" (non-face-to-face real time contact) mode of AW. Also, seeing the various submitted lesson videos of other students, and the individual feedback given, is extremely helpful. This simple exercise is not quite so simple; I thought I would just bang it out in 5 minutes, but that is not the case.
I searched the pianostreet forum for something on this new course I just started, and only found this previous post, so I wanted to offer an additional point of view.
If anybody here is currently using AW with Christine Peery, I am interested in hearing of your experience.
