Hungary has made many contributions to the fields of folk, popular and classical music. Hungarian folk music is a prominent part of the national identity and continues to play a major part in Hungarian music. It is also strong in the Szabolcs-Szatmár area and in the southwest part of Transdanubia. The Busójárás carnival in Mohács is a major Hungarian folk music event, formerly featuring the long-established and well-regarded Bogyiszló orchestra. Hungarian classical music has long been an "experiment, made from Hungarian antedecents and on Hungarian soil, to create a conscious musical culture [using the] musical world of the folk song". Although the Hungarian upper class has long had cultural and political connections with the rest of Europe, leading to an influx of European musical ideas, the rural peasants maintained their own traditions such that by the end of the 19th century Hungarian composers could draw on rural peasant music to (re)create a Hungarian classical style. For example, Béla Bartók and Zoltán Kodály, two of Hungary's most famous composers, are known for using folk themes in their music. Bartók collected folk songs from across Central and Eastern Europe, including the Czech Republic, Poland, Romania and Slovakia, whilst Kodály was more interested in creating a distinctively Hungarian musical style. During the era of Communist rule in Hungary (1949–1989) a Song Committee scoured and censored popular music for traces of subversion and ideological impurity. Since then, however, the Hungarian music industry has begun to recover, producing successful performers in the fields of jazz such as trumpeter Rudolf Tomsits, pianist-composer Károly Binder and, in a modernized form of Hungarian folk, Ferenc Sebő and Márta Sebestyén. The three giants of Hungarian rock, Illés, Metró and Omega, remain very popular, especially Omega, which has followings in Germany and beyond as well as in Hungary. Older veteran underground bands such as Beatrice from the 1980s also remain popular. Characteristics Unlike most Western European peoples, the Hungarian people, Magyars, emerged from the intermingling of Ugric and Eastern Turkic peoples peoples during the fifth to eighth centuries AD. This makes the origins of their traditional music unique in Europe. According to author Simon Broughton, the composer and song collector Kodály identified songs that "apparently date back 2,500 years" in common with the Mari people of Russia; and, as well as the Mari, the ethnomusicologist Bruno Nettl indicates similarities in traditional Hungarian music with Mongolian and Native American musical styles.
