Ganga is a type of singing from rural Croatia and Bosnia and Herzegovina. It is characterized by a lone singer singing one line of lyrics and then others joining in for what can be best described as a wail. It is a very passionate form of singing, which is one of the reasons it has been limited in popularity to small towns.
In the nineteenth century, a new form of ballroom dancing emerged in Croatia. Elements of European ballroom spread throughout the region, and dances such as the polka soon became widspread all throughout the Croatian regions. Croatian ballroom dancing, or salonsko kolo, emerged in the nineteenth century as a result of the above influences. Due to the Croatian national revival and re-awakening of Croatian culture and national identity, an effort was made to incorporate traditional music and dances into the urban dance revival. Thus, the intellectual idealists saw kolo as a quintessential Slavic dance, and chose to adopt it for the urban context it. It was at this time that the hrvatsko kolo emerged as a choreographed dance.
Central European influences are most obvious in the couple dances (mazurka, valcer, polka, schotisch, siebenschritt, rašpa, štajeriš, furlana, palaisglais) in north-western, northern and central Croatia, and in Istria and the Gulf of Quarnero region.
