A pyro-musical choice would be really nice and formal for your wedding, in my opinion. I'm talking from experience here! In addition, it will make the display much more lively, more enjoyable and entertaining, however, it is more costly. As Sean said, though, it can be adjusted to your individual budget.
This depends on you, however. What you find will be more suitable for your wedding is completely up to you. It's totally according to your preferences.
