What's that one classical song that's with strings and starts quiet and slowly grows loude

It starts out quiet with one violin, and slowly grows to add one more violin, then another, and grows louder. Or at least I think its violins -- could be some other type of strings. It kind of builds on layers in the starting. Its really pretty and fairly wide known. You'd probably find it on any classical radio station. I have no idea who the composer is or anything. I just can't for the life of me figure out what the song is. Can someone help?

I bet you're thinking of Pachelbel's Canon in D. If it is, you're right; it's very well known and you'll be able to find a recording with ease. If you can't find a recording, I can hook you up.

Must be Ravel's "Bolero" you are refering to. Became popular when it was featured in the movie "10" starring Dudley Moore and Bo Derek.
The Blue Danube by Strauss? It's a waltz.
Its called Ravell's Bollero
