The Romanian Folk Dances is a suite of six short piano pieces composed by Béla Bartók in 1915. He later orchestrated it for small ensemble in 1917. It is based on seven Romanian tunes from Transylvania, originally played on fiddle or shepherd's flute. Its title was originally Romanian Folk Dances from Hungary but was later changed by Bartók when Transylvania became part of Romania in 1920.
Béla Viktor János Bartók (March 1881 – September 1945) was a Hungarian composer, pianist, and ethnomusicologist. He is considered one of the most important composers of the 20th century; he and Franz Liszt are regarded as Hungary's greatest composers. Through his collection and analytical study of folk music, he was one of the founders of comparative musicology, which later became ethnomusicology. Bartók was born in the Banatian town of Nagyszentmiklós in the Kingdom of Hungary (present-day Sânnicolau Mare, Romania) on 25 March 1881. He displayed notable musical talent very early in life: according to his mother, he could distinguish between different dance rhythms that she played on the piano before he learned to speak in complete sentences. By the age of four he was able to play 40 pieces on the piano, and his mother began formally teaching him the next year. When he was seven, his father, the director of an agricultural school, died suddenly. His mother then took Béla and his sister, Erzsébet, to live in Nagyszőlős (present-day Vynohradiv, Ukraine) and then in Pressburg (Pozsony, present-day Bratislava). Béla gave his first public recital aged 11 to positive critical reception. Among the pieces he played was his own first composition, written two years previously: a short piece called The Course of the Danube. From 1899 to 1903, Bartók studied piano under István Thomán, a former student of Franz Liszt, and composition under János Koessler at the Royal Academy of Music in Budapest. There he met Zoltán Kodály, who made a strong impression on him and became a lifelong friend and colleague. In 1903, Bartók wrote his first major orchestral work, Kossuth, a symphonic poem which honoured Lajos Kossuth, hero of the Hungarian Revolution of 1848.
