What this this song called?

It was on a Macy's commercial advertising Estee Lauder perfume and had a little girl and bride. It was a classical sounding song and is one of the typical wedding songs. Does any know what it is called?

Hey guys! Stop fighting! Goodness! lol

Sorry, but I must disagree with that. Just because there are no lyrics, does not take away from the fact that it is a song(though some would argue that using it to refer to a piece of music that has no lyrics is using it as almost a slang word).
I think I know the song that you are talking about, and I agree with the other answer as I believe it was Canon in D by Johann Pachelbel.
Here is it on youtube-

Hope it's the right song!

If it had no words its not a song. The most common classical pieces used in weddings are: the dreaded Canon in D by Pachelbel, the Wedding March from a Midsummer Nights Dream by Mendelssohn and the Bridal Chorus from Lohengrin by Wagner.

Edit: Outer space, I am sorry - you are just completely wrong. A song may have an instrumental version, but without voice it is no longer a song. This is typical of the iTunes generation, who have to have a catch-all word in the modern pop idiom. I will not stand by and have everybody be wrong. Too many liberties are already taken with the English language.

This is for Outer Space, whio seems to have difficulty with the definition of a song:

1 A song is a relatively short musical composition for the human voice (commonly accompanied by other musical instruments), which generally (exceptions would be scat songs) features words (lyrics)
2 The act of singing; "with a shout and a song they marched up to the gates"

Clear? Just because a word is commonly misused it doesn't make it correct.

get a life sis, rock is the way to go!
