Practice in tranquility.
I always make sure that the lid over the keyboard is open before I start to play.
I know two kinds of audiences only--one coughing, and one not coughing.
I practice in my head.
Sunshine can burn you, food can poison you, words can condemn you, pictures can insult you; music cannot punish - only bless.
It is not music's function to express rational necessities.
