good symphony music with unchanging volume for interrupting a speaker (a la The Oscars)?

Question

Looking for a recommendation of symphony music I can get ahold of to use like the Acadamy Awards show uses to interrupt a speaker after a few minutes. The music needs to ramp up to a pretty regular volume quickly and stay at that volume, so we can gradually turn the volume up on playback and have a predictable experience. Some music we used last time was too dynamic and was thus unpredictable

Answer 1

Would you consider something in the category of "light classical"? If so, I'd suggest "The Syncopated Clock," by Leroy Anderson:



That would lend a touch of humor, as well?!

Answer 2

Try the organ toccata by Vidor.



Good luck
