Headbanging is violently shaking the head in time with the music, most commonly in the rock, punk and heavy metal music genres.
The origin of the term "headbanging" is contested.

During a show at the Boston Tea Party, audience members in the first row were banging their heads against the stage in rhythm with the music.
Ozzy Osbourne and Geezer Butler of Black Sabbath are among the first documented headbangers, as it is possible to see on a band's concert in Paris, 1970.
Lemmy from Motörhead, however, said in an interview on the documentary The Decline of Western Civilization II: The Metal Years, that the term "Headbanger" may have originated in the band's name, as in "Motorheadbanger".
Ian Gillan, frontman of Deep Purple, when asked if he invented headbanging, said: "That's a definite possibility", although he claimed that "it was not really head banging -- more hair floating".
