Kizomba music was born in Angola (in Luanda) in early 80s following the influences of traditional semba with kilapanda and merengue. On this basis, Kizomba music emerged as a more modern music genre with a sensual touch mixed with African rhythm. Unlike Semba, Kizomba music is characterised by a slower and usually very romantic rhythm. Given that Angola is a former Portuguese colony, Portuguese is the principal language spoken in Angola and thus, also most Kizomba songs are sung in Portuguese. However, Kizomba songs at the very beginning were sung in Kimbundu and in other National languages of Angola.
The dance style Kizomba was connected two the music style in 1981, through “Bibi king of the pace” percussionist of the SOS Band, a group that joining other styles such as merengue and Angolan rhythms to others styles developed by other contemporary groups, developing a sound more attractive and danceable that began circulating in the Angolan “Kizombadas” (party’s). One member of this group was Eduardo Paim that after the dissolution of SOS, moved to Portugal leading with him the pace Kizomba, which began garnering fans in Lusitanian lands but mistakenly confused with a variant of Zouk.
