There are five prime classifications of dirge:
1. Trad Dirge
2. True Dirge (also known as Pure Dirge)
3. Dirge (also know as Standard Dirge)
4. Sub Dirge
5. Fake Dirge
However, there are offshoots such as Math Dirge, Nu Dirge, Black Dirge, Dirge Punk, Dirge Core, Neo-Classical Dirge, Prog Dirge, Nintendirgecore etc but they generally are derivative of one of the five main classifications.
