Ceremony music

You can absolutely do just one song if you want. I would say there is typically a different song for family being seated to the bridal party entrance, but I've seen plenty of weddings where the bride entered to the same music as the rest of the wedding party. I've seen everyone also enter to the same song. It's up to you.

I think your music is fine, but if you want to know if they flow well you can put them in a playlist and kind of get a feel for it. Your DJ should be able to put them in and out to an aesthetically pleasing sound though.

You can also look at instrumental versions of the songs, I recommend checking out the Vitamin String Quartet, they do tons of covers as nice string music.

It is completely up to you if you want to do one song. We did two - one for the seating of the mothers and the bridal party and then one for me to walk down the aisle. I think the songs you picked are very pretty. I would recommend speaking with your planner about cueing the DJ.

A violin cover of "My Heart Will Go On" by Taylor Davis. I found it on YouTube when I was looking for instrumental songs. I love Titanic and knew the song was perfect from the moment I heard it.

We did a lot of different music (one song for each: Groom & GM entrance; seating of the parents; BM entrance; bridal processional; and recessional) it worked out quite well.
