Well it's not really a problem because actually when you're looking at the score you always are inspired to use, probably more often than not, things that don't have to be there. The whole idea I find is the simplicity is where you get the most value out of the thing. When you can write simple. That means that when you do write complicated or write the whole ensemble it has more of a purpose. But you can always use, especially if you have good musicians. That's the thing that affects it. The level of musicianship that you're dealing with. You can write one person playing when it's a really good musician, and it will have a good effect. But if it's a musician that doesn't have very much experience and you write them by theirselves it can feel uncertain. But you know all the instruments can always be used in so many ways to make the different colors, the different effects, and to make as much variety as possible. That's very important.
