This is a great point by Mike over at the How to Practise website. I’ve noticed how often my students, who play well with dynamics at their lessons, often can’t get the same good sound when they perform in other venues. I’m definitely going to start using this principle of “no such thing as piano” with my students – in fact I even incorporated it into a student’s lesson yesterday! – and see how they do.
BTW, if you haven’t checked out Mike’s website, be sure you carve out about three hours (or maybe three days!) and treat yourself to all kinds of helpful information and practice tips. It’s loaded, and I haven’t even begun to scratch the surface of everything the site has to offer. Not to mention that I love the colors and layout of the site!
