Moshing is a style of heavy metal or hardcore dancing that originated in the world of hardcore in the 1980’s. It soon filtered into the thrash metal and death metal scenes. In the 1990’s grunge would adopt moshing as an outlet for angsty teenage fans. From there it would filter into most of the more aggressive forms of heavy metal, like nu metal and metalcore. Moshing is usually done at live shows in what is called a mosh pit. This is a grouping of fans that forms a circle where participants aggressively push and slam into each other. Moshing can be done during slow tempo breakdowns or during fast and upbeat thrash riffs. The speed and aggressiveness of the moshing is dependent on the tempo of the song. Believe it or not, there are unwritten protocols in the world of moshing. The most important rule is that no one deliberately tries to hurt another. Therefor moshing fits into the sense of community and camaraderie that most metal fans have become accustomed to.
