It is unnecessary to review the history of portrayals of the Gypsy woman as a bedeviling chanteuse, perhaps the two most famous examples being Esmeralda from Hugo's The Hunchback of Notre Dame and the title character from Bizet's opera Carmen. There seems to be more than a grain of truth to the archetype, though, as I've found by looking through YouTube for videos of contemporary female Gypsy singers.
To briefly review their history, the Gypsies (or Roma, as we're now supposed to call them) left the Indian subcontient somewhere between 800 and 900 years go, meandered through the Middle East, and arrived in southeastern Europe and Anatolia, where most of them remain, although Spain has a large population as well. (Here is a free human genetics article on the topic.) Their influence on popular and high forms of music is disproportionately large, given the fraction of the European population they represent, and given that one recent estimate of their mean IQ is 70 (or 2 SD below the European mean), though presumably better health and nutrition would raise it by perhaps 5 points.
All right then, let's take a look and see why images of Gypsy women as enchanting songbirds have become so common, using contemporary pop music stars as exemplars. The "tour" is done in descending order of pulchritude, as I see it. All of these women are really worth a follow-up YouTube or Google Image search, but I only show one video per person so as to contain the clutter.
To begin, marvel at the turquoise eyes of Eirini Merkouri (first name also spelled Irini), who is Greek in nationality and language (a duet):
Next is Reyhan, who was Bulgarian in nationality but sung in Turkish. She's the brunette (an earlier, more plaintive video):
Although only half-Gypsy, Edyta Gorniak is too alluring and melodious to pass up on technicalities. She's Polish in nationality and language (another video):
Lastly, Sofi Marinova is Bulgarian in nationality and language (another video that better shows off her elegantly elongated Perso-Indic schnoz):
