The first official song both you and your partner are going to hear is the song you walk down the aisle to. Next to your bridal waltz, this is the most important song of your entire wedding and deserves a little bit of thought.
You have two options- do you want to walk down to instrumental or to a song with lyrics?
There are so many versions of well known songs done on guitar, as an instrumental, on piano or on strings...so once you decide, it is simply a matter of finding the version you like the best for walking down the aisle.
