What makes a good pianist?
When I was a kid, my family could only afford to send one child to private lesson- it was expensive-and my older sister got to be the one to go. It seemed like going to get some privilege that I was not going to get, so I threw a temper tantrum for several days. I was four years old. Fnally my Dad said, “OK,OK, OK, just be quiet, you can go,.” And after the second lesson I wanted to stop, because I didn’t know you were supposed to come home every day and practice. So I said, “Thanks, Dad, but now I don’t want to do it,” and he said, “ Oh no, no,no , it doesn’t go that way.” So from four years old until about eleven years old, playing the piano was not fun. I mean, there were other things that I thought I should be doing.
At 11 years old I started studying at the musical college which is now the musical college of Roosevelt University. That’s when the things changed. I started hearing things within the music then and started seeing things between the notes. I got to there instead of my parents saying, “You’d better go there and practice”. They would say, “Hey, it’s 11 o’clock, don’t you want to stop practicing now?” The tabes had turned. I could just sit at the piano for hours. I loved the sound of it, the feel of it.
