Nowadays, belly dance is a predominantly female art form; however, in the past it was not so. In belly dance’s countries of origin (Egypt and Turkey) men used to perform the same type of dance that women did and also they could perform for a male audience, which female dancers did not always do. Hence, male dancers were in demand. It was only with the arrival of westerners that male belly dancers became fewer and fewer, as westerners preferred to watch women dancing. Also, the mentality in Turkey and Egypt changed, so that nowadays in those countries men only perform folkloric forms of dance, rather than raqs sharqi. Men also dance socially to shaabi music, using some movements that are typical of what we know today as belly dance.
Nevertheless, there are now more and more performers from various countries in the world, who perform belly dance in its different forms. They perform folkloric dances, as well as raqs sharqi and American tribal, which was traditionally reserved for women. Currently, there are several male belly dancers around the world. Below a list of 10 I know of. If you know any more, please feel free to add your comment below.
In addition to the dancers above, there are of course many more, whom I have come across through Youtube. One who is extremely good and who is in demand worldwide is Egyptian dancer Tito. Other male dancers include, Zack (tribal dancer from Texas), Said Rashid and Samir Abut from Argentina (who both run belly dance schools there) and Jimmy from Greece just to name a few.
In terms of dance in the community and local belly dance classes, I still have not been in a class where there are male dancers, nor have I seen anyone perform at a local hafla. However, I think it is just a question of time and we will see more men joining the belly dance community.
