Calling All Music Geeks

You know the song "Hook" by Blues Traveler? If you listen to the opening chord progression, it's basically a direct ripoff (or "homage" if you like) of a famous classical song that I don't know the name of.

It (the classical song) shows up at a lot of weddings. It's really slow and sweet-sounding. The first four bars are each two long notes, and then in the next four bars it breaks into a bunch of shorter notes overlaid on the long notes. Kind of like this:

|Dooooooo dooooooo|dooooooo dooooooo|
|Dooooooo dooooooo|dooooooo dooooooo|
|Do do-do-do do-do-do do-do-do-do-do-do|do do-do-do do-do-do do-do-do-do-do-do|
|Do do-do-do do-do-do do-do-do-do-do-do|do do-do-do do-do-do do-do-do-do-do-do|

I can't find a MIDI of "Hook," or else I'd post it. Any ideas on the name of the classical song? It's really driving me crazy.

My blog is dumb.
