The set of ten Hungarian dances opens with the famous G minor dance, followed by a D minor dance, with a central D major episode, and a third in D minor, with a lively D major middle section. The fourth dance, in F sharp minor, is of a more expressive cast, leading to a more passionate companion in the same key. The sixth of the set, in D flat major, frames a slower C sharp minor section in livelier outer sections, leading to the rhythmic seventh dance and an eighth in A minor in the rhythm of the first. A dance in E minor is succeeded by the final rapid E major that rounds of the work. The sixteen Waltzes that form Opus 39 were written in Vienna in 1864 and published two years later with a dedication to the critic Eduard Hanslick, who welcomed such an unexpected gift from a serious, North German composer, who might have been supposed incapable of such Viennese abandon. If the great symphonies of Brahms continue the tradition of Schubert, they may be imagined as a tribute to the city where the compose was now to make his home. The original version seems to be that for piano duet, a form that had an immediate popular commercial attraction and would have provided Hanslick with music to share with young ladies of his acquaintance, with whom he was accustomed to play duets. The Waltzes are in a simpler and shorter form than the slightly more complex Hungarian Dances. Idil Biret born in Ankara, Idil Biret began piano lessons at the age of three.
