In my latest peruse through the internet, I found a fabulous site - Pianocareer.com. The author, Ilinca Vartic is a Russian pianist and teacher. I read through her recent posting on the use of the piano pedals and then watched the videos. She is wonderfully articulate and does a beautiful job of explaining the techniques and the mechanics of the pedal. I immediately thought the videos would be a great addition to a group class for intermediate and advanced students.
She also has several other articles that I briefly looked and also seem well done. I'm looking forward to checking her site more closely. As an added bonus, if you subsribe to her site, she will send you a free download - "A New Perspective on Piano Phrasing: How to Transform a Boring Performance Into a Captivating One in 3 Creative Steps"!
If you haven't seen it yet, I would encourage you to head on over and take a look!
