"dance house") is a dance music movement which first appeared in the 1970s as a reaction against state-supported homogenised and sanitised folk music. They have been described as a "cross between a barn dance and folk club", and generally begin with a slow tempo verbunkos (recruiting dance), followed by swifter csárdás dances. Csárdás is a very popular Hungarian folk dance that comes in many regional varieties, and is characterized by changes in tempo. Táncház began with the folk song collecting of musicians like Béla Halmos and Ferenc Sebő, who collected rural instrumental and dance music for popular, urban consumption, along with the dance collectors György Martin and Sándor Timár. The most important rural source of these songs was Transylvania, which is actually in Romania but has a large ethnic Hungarian minority. The instrumentation of these bands, based on Transylvanian and sometimes the southern Slovak Hungarian communities, included a fiddle on lead with violin, a kontra (a 3-string viola also called a brácsa), and bowed double bass, and sometimes a cimbalom as well. Many of the biggest names in modern Hungarian music emerged from the táncház scene, including Muzsikás and Márta Sebestyén. Other bands include Vujicsics, Jánosi, Téka and Kalamajka, while singers include Éva Fábián and András Berecz. Famous instrumentalists include fiddlers Csaba Ökrös and Balázs Vizeli, cimbalomist Kálmán Balogh, violinist Félix Lajkó (from Subotica in Serbia) and multi-instrumentalist Mihály Dresch. Classical music Hungary's most important contribution to the worldwide field of European classical music is probably Franz Liszt, a renowned pianist in his own time and a well-regarded composer of 19 Hungarian Rhapsodies and a number of symphonic poems such as Les préludes. Liszt was among the major composers during the late 19th century, a time when modern Hungarian classical music was in its formative stage. Along with Liszt and his French Romantic tendencies, Ferenc Erkel's Italian and French-style operas, with Hungarian words, and Mihály Mosonyi's German classical style, helped set the stage for future music, and their influence is "unsurpassed even by their successors, because in addition to their individual abilities they bring about an unprecedented artistic intensification of the Romantic musical idiom, which is practically consumed by this extreme passion". Elements of Hungarian folk music, especially verbunkos, became important elements of many composers, both Hungarians like Kalman Simonffy and foreign composers like Johannes Brahms and Ludwig van Beethoven. Hungary has also produced Karl Goldmark, composer of the Rustic
