Bulgarian music is part of the distinctive Balkan musical tradition and uses a wide variety of traditional instruments. Traditional Bulgarian vocals are described as "open-throated" and focus the voice in a way that allows it to carry over long distances. Some common traditional Bulgarian instruments include the gadoulka (a stringed instrument without frets), the kaval (a woodwind instrument), the gaida (bagpipe), the tapan (drum), and the tamboura (a stringed instrument). Modern Bulgarian music has also incorporated more modern dance styles and instrumentation.
