"Galdr" is another Heathen practice involving chanting or singing. As part of a "galdr" ceremony, runes or rune poems are also sometimes chanted, in order to create a communal mood and allow participants to enter into altered states of consciousness and request communication with deities. Some contemporary "galdr" chants and songs are influenced by Anglo-Saxon folk magical charms, such as "Æcerbot" and the "Nine Herbs Charm". These poems were originally written in a Christian context, although practitioners believe that they reflect themes present in pre-Christian, shamanistic religion, and thus re-appropriate and "Heathanise" them for contemporary usage.
