In wealthy homes and vocal performers of musical works are usually (as in many homes now) were domestic slaves, well-trained specialists hired his art, men and women. In fairy tales "Thousand and One Nights" are a slave, as a rule, stand or sit without a veil in the presence of the male guests. But a series of musical performances descriptions that I have seen in the works of Arab historians, it turns out that in a respectable society was made to the performers in such cases hiding behind the curtains, which are normally closed entrance to the premises, elevated above the rest of the. In all the homes of the rich Arabs, which I attended, one or each of the great halls had raised an isolated room, the entrance to which is covered wooden lattice screen view. This room served as a stage for domestic or hired singers and musicians.
