An Amish wedding is primarily a service. Three hours. Hymns, sermons, prayers. Bride and groom sit in the Eck (corner of honor) and listen.
Which Hymns
Lob Lied (mandatory). Ausbund hymns about marriage, faithfulness, family. Slow as always. Community sings — bride and groom are silent.
Why Silent
The day belongs not to them but to God and community. Bride and groom are the center but not the main characters. God is — who joins them. Singing themselves = drawing attention = Hochmut.
