Ok this is kind of a hard one, first off, i dont think its copyrighted and if it is then I wouldnt know by who or where to buy this even if i could so as far as i know this is free to public access....

That music that plays like when horses are racing, or on those stupid things kids sit on in supermarkets with the horse... i need that song... i cant exactly type the way it sounds... but maybe someone will know what i mean...

I do know its orchestrated.

any help would be great, i already searched google... didnt help.

You dont mean the William Tell Overture do you?

Also, moving this to the music forum.

Maybe this website will help: http://www.name-this-tune.com/

duh du-du-duh du-du-duh du-du-dah dah!

Dum da da Dum da da Dum Dum Dum!

William Tell Overture.

If you check out the link I posted, you can actually search by something like the "da da dum".

You use an asterik for the first note, than u if the next is higher or d if it's lower.
