A second marriage is different. Both partners have lived a life. The song that lands there cannot pretend this is anyone's first wedding. A custom song for a second marriage honors the years that came before — the kids, the previous chapters, the things learned — alongside the union being made.
What this kind of song holds
These songs hold the maturity. They hold the gratitude that this is happening at all, after everything. They hold the kids (if there are kids) and the chapter that closed (if naming it serves the song). They hold the calm certainty that doesn't come in a first marriage.
What to put in the intake
Tell us the years between this wedding and the previous. Tell us the kids (if you want them named or honored). Tell us what you know now that you didn't know then. The song writes from the specific maturity of a second wedding, not from a borrowed first-wedding template.
