I can't tell you how much I appreciate your following up with me and the ongoing advice and bonus material you have provided. I am a guitarist who is studying piano and music theory and, while I have used online teaching materials before, I have never experienced an online teaching service that actually follows up with students. I appreciate it very much. Also, I am finding your lessons to be some of the best I've encountered in terms of being clearly presented and easy to follow while also maintaining a high level of challenge and sophistication. I am looking forward to more. Thanks so much.
