The thing that I've always been slightly frustrated with, was that the idea of a CD is kind of confined to a material possession that you can put on a shelf. And the idea of music, for me, is always about both the communication and the sharing of content. And so the interactive part is missing.

People will ask, 'Are you famous?' And I always answer, 'My mother thinks so.'

Passion is one great force that unleashes creativity, because if you're passionate about something, then you're more willing to take risks.

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.

As you begin to realize that every different type of music, everybody's individual music, has its own rhythm, life, language and heritage, you realize how life changes, and you learn how to be more open and adaptive to what is around us.

Mastering music is more than learning technical skills. Practicing is about quality, not quantity. Some days I practice for hours; other days it will be just a few minutes.

One of the things I love about music is live performance.

I think the purpose of a piece of music is significant when it actually lives in somebody else. A composer puts down a code, and a performer can activate the code in somebody else. Once it lives in somebody else, it can live in others as well.

Music is powered by ideas. If you don't have clarity of ideas, you're just communicating sheer sound.

Music has always been transnational; people pick up whatever interests them, and certainly a lot of classical music has absorbed influences from all over the world.

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.

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 one of the great things about being a musician is that you never stop learning.

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.

Things can fall apart, or threaten to, for many reasons, and then there's got to be a leap of faith. Ultimately, when you're at the edge, you have to go forward or backward; if you go forward, you have to jump together.

I love grocery shopping when I'm home. That's what makes me feel totally normal. I love both the idea of home as in being with my family and friends, and also the idea of exploration. I think those two are probably my great interests.
