I found through Wendy Steven's website, a magazine that is devoted exclusively to the concerns of the piano/keyboard performer and teacher - Clavier Companion. The site actually allows you to read previous copies. It is published bi-monthly and I just subscribed to it. I'm looking forward to receiving my first copy!
You can view the copies and read the articles here:
2012 online issues
2011 online issues
I have yet to go through all the magazines. There are so many interesting topics in EACH copy that I'm having a hard time deciding which one to read first. For example, in the March/April 2011 copy, there's a section dedicated to Perspectives in Pedagogy where the Bastien Piano Series is evaluated by two teachers who have used this method extensively. It is then followed by the author's response. This is interesting because I do like the Bastien series very much myself. That and Piano Adventures. Now, I just need to find the time (in between work, chores, and taking care of my 3 month old) to sit down and read a complete article!
Let me know if you had an opportunity to read an article from Clavier Companion that you particularly like. I would love to hear what you think.
