In teh conductor`s score, can I leave each staff in concert pich, or must I go ahead and transpose each staff for its respective instrument. I know it`s usually transposed, but somebody told me that they`ve seen it the other way before.

Also, can anybody tell me what key the Viola is written in? And if it MUST use alto clef, or viola can also read treble?

Also, I want to make sure of the ranges for violin, viola, and cello before I go ahead and print this 44 page piece out. Thanks!
