Genres of blues include the following: There are several genres unrelated to the blues in any factual sense but are described as blues-like or bluesy. These are typically urban in origin, simple in instrumentation and featuring plaintive, melancholy vocals that emphasize the singer's poor luck and, often, violent or criminal behavior. Anthropologist Joaquim Reis de Brito describes the phenomenon thusly:

Thus, if we take together the Fado of Lisbon, the Tango of Buenos-Aires and the Rembetika of Athens, we will note firstly that all of them emerged a little before or after the middle of the 19th century in poor districts of the big port cities of the nascent industry, attracting people from the country or from abroad, and who were confined to a marginal existence. And if we look for other parallels in the development of these urban popular cultures, we will find them again: first, their obscure and repressed beginnings, then their discovery and appropriation by elements of the higher social classes, later their acceptance and admission by the establishment (often after their success outside of the native land) before ending as a subject of tourist explorations.

Note that not all of the characteristics above are common to all the genres compared to blues, and not all are true of the blues itself.
