They are just different words that some orchestras use to describe themselves. We have the Boston Symphony and the New York Philharmonic. It's just a different use of words. It places demands on you because we go on tour for about three and a half weeks at a time. Women who have had newborns sometimes take the baby on tour or else don't go on tour.
Some mothers go without their baby, depending on the age, and that's stressful as well.
This week we are playing a work by the conductor Andre Previn. He's conducting this week, so the first piece is a composition by him. I want to add that a lot of the works we play, I have played many times before. So the preparation varies, depending on whether we are playing an old piece or a new piece that's difficult or easy. It's a project I keep saying I'm going to do and haven't gotten around to it, but I want to make a recording.
