The role of the musician is to go from concept to full execution. Put another way, it's to go from understanding the content of something to really learning how to communicate it and make sure it's well-received and lives in somebody else.

My teacher, my great cello teacher Leonard Rose, was such a great cellist, and nurturing man, very patient. But I grew up not only admiring him, but obviously Casals, Rostrotovich, Jacqueline du Pre, and many others, including many of my peers and contemporaries.

I think there are so many ways to become interested in music. I believe signs of sustained interest gives a sense of the right time. Music, if thought of as a language, would perhaps indicate that as early as possible is not so bad. I do believe that a really nurturing first teacher that makes the child love something is crucial.

One is that you have to take time, lots of time, to let an idea grow from within. The second is that when you sign on to something, there will be issues of trust, deep trust, the way the members of a string quartet have to trust one another.
