Melodic death metal (also referred to as melodeath or MDM) is a subgenre of heavy metal music that combines death metal with the melodious and harmonic elements of the new wave of British heavy metal. The style originated and developed in Sweden (pioneered by At the Gates, Dark Tranquillity and In Flames) and the United Kingdom (pioneered by Carcass) during the early and mid-1990s. The Swedish death metal scene did much to popularize the style, soon centering in the "Gothenburg metal" scene.
