ELI5: Explain Like I'm 5

Processional hymn

A processional hymn is a special song that is often sung while people, like you and me or other grown-ups, are walking or processing from one place to another. This could be at church or at a special ceremony. It is usually a happy song and helps get everyone in a good and happy mood. Sometimes, people will sing along or clap their hands to the music. It's kind of like a happy song to help celebrate and bring people together.
