Voodoo
In voodoo many gods and spirits are prayed to or called on.  Both spirits of nature and of dead people are important.  The spirits of family members who have died are especially important.  Voodoo often has rituals with music and dancing.  Drums are used to make most of this music.  In voodoo people often believe that a spirit is in their body and controlling the body.  Having a spirit come into is wanted, and important.  This spirit can speak for the gods or dead people you love, and can also help to heal or do magic.
