Funeral customs vary widely between cultures and even within cultures.
A good example of this in the United States is the custom of "Jazz Funerals" in New Orleans, Louisiana.
A jazz funeral happens in two parts: a mourning the death part and a celebrating the life part.
The tradition arises from African spiritual practices, French and Spanish martial musical traditions, and uniquely African-American cultural influences. The tradition was widespread among New Orleanians across ethnic boundaries at the start of the 20th century.
Funeral flower arrangements for a Jazz Funeral should be festive.
