Welcome to LivingPianos.com, I’m Robert Estrin. The subject today is about how dynamics are like orchestration in your music. The piano is an amazing instrument because you have all the parts of a whole orchestra right under your fingertips! You want to think of your playing as orchestrating the sound and getting the quality of different sections of an orchestra—the strings, the brass, the percussion, all of it.
