Funeral doom is a style of doom metal that crosses death-doom with funeral dirge music. It is played at a very slow tempo, and places an emphasis on evoking a sense of emptiness and despair. Typically, electric guitars are heavily distorted and dark ambient aspects such as keyboards or synthesizers are often used to create a "dreamlike" atmosphere. Vocals consist of mournful chants or growls and are often in the background. Funeral doom was pioneered by Mournful Congregation (Australia), Esoteric (United Kingdom), Evoken (United States), Funeral (Norway), Thergothon (Finland), Skepticism (Finland) and Corrupted (Japan).
