Bistritsa Babi
Bistritsa Babi are an elderly/multi-generational female vocal ensemble carrying on the traditional dances and polyphonic singing of the Shopluk region of Bulgaria. Founded in 1939, the group won the European Folk Art Award in 1978, and it was declared a Masterpiece of the Intangible Heritage of Humanity in 2005. Performing three-part polyphony with features "retained from the pre-Christian times," the group has toured Europe and the US. They are known for their use of Shopi polyphony, costuming, dancing in a ring, and performing the lazarouvane. In 2005 they were included in UNESCO List of Intangible Cultural Heritage elements in Eastern Europe.
The Shopi genre is characterized by diaphony and parallel voicing. "Diaphony" is a type of polyphony where the melody is performed by one or two soloists, consisting of izvikava and buchi krivo or "to shout out" and "crooked rumbled roars", while the ensemble holds a doubled or trebled drone. Dance and music are asynchronous.
The group was formed by pairs of women recruited as vocal accompanists to the Bistritsa Chetvorka, founded around 1935.
