Chefera is a single performed poem which an individual sings in verses that can be considered as societal critic of to any behavior that the singer considers to be inappropriate, immoral or deviating from the traditional norms and values that the Blin people consider to be commonly accepted, and based on what is expectation that the society should be free of corruption. Especially targeted behavior is ethical and moral issues that deviate from the norms, values, and rules accepted of the community. Political, religious, economic and other social issues may also be singled out and commented upon. The behavior of young ladies, unmarried ladies also one of the famous topics that a Chefera singer targets for criticism. Much of the criticism is exaggerated, rhetorical, and often ironic, with some realistic part often included. Chefera may be a serious comment, just for entertainment, or just ironic depending upon the audience, the fashionability of the issues that may tend to be attractive just at that time, or they may be long-term issues that contain historical or probable future events.
Time is often an important element as far the songs comment on what was in the past, what is today, and what the future prospects of a particular issue may be. Traditionally, Blin elders did not encourage their own relatives to be Chefera singers probably due to the bad linkage it may have with singers whose status once upon a time was not liked. Additionally, Chefera singers target certain behavior as inappropriate and, in return, they may risk being targeted for criticism, and the relatives would like to avoid joining it altogether. In spite of all such reluctance, Chefera has remained as one of the main entertainment poems and a serious societal critic, or moral rearmament of each period of time.
