Welcome to LivingPianos.com, I’m Robert Estrin. Today’s topic is about the power of musical snippets in your practice. What you’re going to learn today is one of the most valuable techniques you could ever use in your piano practice. The amazing thing about it is that you can use this technique with almost all of your music! It’s incredibly valuable, especially for something fast. I’m going to play the beginning of the B minor Scherzo of Chopin. It’s a little rusty, so I can practice it in front of you. You can see for yourself how this technique works in the accompanying video.
