Shrink score to fit on page?
I need to email a PDF of the score of an orchestral composition I am writing to submit it to a competition. Unfortunately, it doesn't fit on a letter-sized page and I assume it will need to be letter-sized in order to be used by the conductor if it is selected to be performed. Is there a way to shrink the score so it fits? (The MuseScore preset "Concert Orchestra" does this perfectly fine, fitting 26 different staves on top of each other on a letter-sized page.)
I appreciate any help.
