Heavy metal singing
Heavy metal singing is a style of singing associated with heavy metal music.
KSL-FM states that heavy metal vocals are a distinct style from what are considered "clean vocals", in that they are generally harsher-sounding and that they "contract their airways in different ways." The publication states that an understanding of vocal pedagogy and proper technique is necessary for a vocalist to achieve the "trademark" sound associated with heavy metal. Hair metal, by contrast, is associated with a "crooning" style of singing, according to Loudwire.
According to Decibel, singing and clean vocals are less common in heavy metal music than they were during the genre's infancy.
