The ''Hungarian Dances'' were published in three different, yet authentic versions during the composer's lifetime: (1) all 21 dances arranged for piano duet, (2) nos. 1-10 also for solo piano and (3) nos. 1, 3 and 10 as orchestral arrangements. Now the Wiener Urtext Edition presents both the piano versions (for 2 and for 4 hands) in new editions and the piano duet version appears here for the first time in the form of a score, i.e. primo and secondo are set as pairs on one page and not, as usual, separated on facing pages. This layout mirrors that of Brahms's surviving autograph of versions 1 and 2 but, additionally, offers significant advantages for study and performance: clearer presentation of the entire composition, easier orientation, no more frantic counting during rests in one part, thanks to the easy legibility of the portrait-format music both players can be more ''in tune'' with each other.
