I had the thrill of my violin-teaching life last week when I taught Kreutzer #4 for the first time.
My 16-year-old student got the hang of up-bow staccato right away, and the beauty of it all is that I didn't need to teach him anything: doing this stroke was extremely natural for him. Today, on a lark, I asked him to reverse the bowing and play the staccato notes down-bow. He did it instantly. Cleanly. Evenly. I made it clear to him that most people (like me) have to work on this stroke a great deal.
He suggested that his aptitude for this might have to do with the fact that he can juggle.
I wonder . . .
