Clean vocals
Also called "cleans". Used mostly in the metalcore and post-hardcore community to describe regular singing, as some artists/bands in these genres often use screamed/growled vocals alongside regular singing.
Example:
"This band has pretty average screams, but the clean vocals are pretty good"
"The singer has really bad cleans"
"This band has pretty average screams, but the clean vocals are pretty good"
"The singer has really bad cleans"
