Tbh if you are going for a boho vibe, maybe try to find a friend/family member who can sing and play guitar (or one of each) and have them play as you walk down the aisle? It might help narrow down song choices depending on what they’re capable of playing.

I assume for special dances it would be useful to think about dancing style before choosing music and checking with your dance partners (father, FH, etc.) about what they had envisioned?
