Kizomba origins from Angola in Afrika and is often sung in Portuguese (and in between in French due to the influence from Zouk music from Guadeloupe). It has spread over Europe through the 00’s and is now a big part of the Salsa festivals. The popularity can be caused by the feeling with the music which has a heavier beat and is influenced by pop music and the R&B genre.
Kizomba is a close partner dance and is slower than both Salsa and Bachata. It is lead by the man in a closed, angled position, a bit like the Argentinian Tango. The basic step is from side to side (1-2, 1-2), but as soon as you continue dancing the beat changes to 1-2-3, 1-2-3-4-5-6-7 etc. The most common step is the Saida.
Among famous Kizomba dancers are Sara Lopez.
