Eloping, Music for Walking Down The Aisle

We are eloping in less than 2 weeks and I just realized that we don't have any plans for any music for us to walk down the aisle to. We will be outdoors with just the officiant, couple witnesses and photographer. Before the ceremony we will do a first look and walk down the aisle together immediately following. We will be in costa rica and in the afternoon. There may be sounds of toucans but otherwise nothing. I think we would like some music but I'm not sure what... would it be odd to not have music? Thoughts?
