The music of Bulgaria refers to all forms of music associated with Bulgaria like classical, folk, popular music, etc. Bulgarian music is part of the Balkan tradition, which stretches across Southeastern Europe, and has its own distinctive sound. Traditional Bulgarian music has had more international success, due to the breakout international success of Le Mystère des Voix Bulgares, a woman's choir that has topped world music charts across Europe and even farther abroad.[1]
Bulgarian vocals are said to be "open-throated", though this is somewhat of a misnomer. Singers actually focus their voices in a way that gives the sound a distinctive "edge", and makes the voice carry over long distances.
