Talk:Heavy metal (music)

• In the Heavy metal (music) article, Heavy Metal and Black Metal are said to (only) belong to the same family. On the other hand, it is said in the Black metal music article that it is a subgenre of Heavy metal. Isn't there a light contradiction here?

• Could someone tell what is the difference between Heavy metal and Hard rock?

• Is Speed metal a subgenre of Heavy metal? Which bands?

Thanks for the clarifications! - User:Olivier
