The Polish Maestro had some interesting things to say about music:
Simplicity is the highest goal, achievable when you have overcome all difficulties. After one has played a vast quantity of notes and more notes, it is simplicity that emerges as the crowning reward of art.
Put all your soul into it, play the way you feel!
It is dreadful when something weighs on your mind, not to have a soul to unburden yourself to. You know what I mean. I tell my piano the things I used to tell you.
There are certain times when I feel more inspired, filled with a strong power that forces me to listen to my inner voice, and when I feel more need than ever for a Pleyel piano.
