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.

"This band has pretty average screams, but the clean vocals are pretty good"
"The singer has really bad cleans"
