I just heard this Bulgarian folk melody, it´s a very special music sung by pretty maidens in their national dresses. It appeals to me too.... I must hear it several times to recognize the subtleties!
By the way, I visited a concert of pupils coming from the Czech Republic who are Roma a few weeks ago. They sang their songs with fervor, it was very interesting and touched all the audience! Their teacher was a woman, also Roma, she works with children since 25 years, some of the kids were street children. It is nearly impossible for her to sing the Roma songs publicly in her home country because Roma people still are not very viewed. It was a special experience!
