melody to their otherwise purely percussive raps whereas some rappers such as Cee-Lo Green are able to harmonize their raps with the beat. The Midwestern group Bone Thugs-n-Harmony was one of the first groups to achieve nationwide recognition for using the fast-paced, melodic and harmonic raps that are also practiced by Do or Die, another Midwestern group. Another rapper that harmonized his rhymes was Nate Dogg, a rapper part of the group 213. Rakim experimented not only with following the beat, but also with complementing the song's melody with his own voice, making his flow sound like that of an instrument (a saxophone in particular).

James Brown had the lyrics, moves, and soul that greatly influenced a lot of rappers in hip hop, and arguably even started the first MC rhyme. For some rappers, there was a distinction to the term, such as for MC Hammer who acquired the nickname "MC" for being a "Master of Ceremonies" which he used when he began performing at various clubs while on the road with
