How to Perform Expressions Like a Professional Pianist?
I know that (usually) the expressive part of classical piano playing is left up to the player with maybe some light guidance from their teacher at some point.
Still I've noticed professional players tend to do certain things that, while subtle, appear to me to have been learned.
Am I correct to think there is some sort of formal training that is usually reserved for people who reach advanced levels?
Are there any educational materials in regards to expression for amateurs interested in more than just simply go at it by feel?
Thank you for your time.
