The band is known for their vocal interplay within the songs, usually having 2, 3, and sometimes 4 rappers in a single song, while one member sings the choruses. However, some tracks are left to a single rapper, such as Johnny 3 Tears in "Pour Me," or Charlie Scene in "Everywhere I Go." And two of the songs, "Christmas in Hollywood" and "The Natives," feature all six of members, including former seventh member Shady Jeff. Guitarist Charlie Scene is known for taking part in the party-based songs such as "Everywhere I Go" or "Comin' in Hot," but did not have a role in "California," "My Town," and "One More Bottle." Charlie also has roles in some more serious songs such as "City" and "Been to Hell." Johnny 3 Tears usually takes part in the more serious and heavier tracks, such as "Young" and "S.C.A.V.A." Johnny 3 Tears usually has a vocal role in all more serious Hollywood Undead songs, but he did not have a role in "Knife Called Lust" or "Lights Out," and has had vocal roles in five party songs, "No. 5," "Bitches," "Tear It Up," "My Town," and "One More Bottle." Funny Man takes part in mainly the party-based songs such as "Comin' in Hot" and "No. 5", usually teaming up with Charlie Scene, did have a role in three serious songs, "The Natives," "Dove and Grenade," and "Lights Out," not including cover songs.
J-Dog is known for his roles in the more fast-paced songs, such as "Sell Your Soul" and "From the Ground," and also takes roles in heavier songs, similarly to Johnny 3 Tears. Although Da Kurlzz doesn't take part in rapping much, he usually provides screaming for songs like "Pain." Before he left the band, Shady Jeff screamed in songs such as the old version of "The Natives" and "Turn Off The Lights," in addition to rapping in "Scene for Dummies." All of the members have screamed in at least one song except for Funny Man, who may scream during live performances of "City" and "Been to Hell," but never on any CD tracks of Hollywood Undead's songs. Danny (and formerly Deuce) provides singing vocals for the choruses in every song with Charlie Scene providing back up vocals in live performances. Both Danny and Deuce screamed in a few songs, Danny raps in one song, "Believe," and Deuce rapped in a few songs before leaving Hollywood Undead. However, in the songs "Bullet" and "Rain," Charlie Scene sings the choruses, or in the songs "Everywhere I Go," "Comin' in Hot," "Another Way Out," and "Medicine," in which he sang clean vocals for an introduction, bridge, or conclusion, while Deuce or Danny sings the chorus. In the songs "Bad Town," "El Urgencia," and "Immigrant Song," J-Dog sings the chorus, tag-teaming with Charlie Scene in "Bad Town" and "El Urgencia," including a duet with Charlie during the final chorus in the song "El Urgencia." Former lead singer Deuce was the only member to perform in the song "This Love, This Hate," rap and clean vocals.
