Brahms' Hungarian Dances count on brilliant and spirited virtuosity whereas his 16 Waltzes, Op. 39 are more modest and intimate.

His publisher must have had an inkling of the success of this collection, as shortly after its publication in its original version for piano four hands in 1866, he asked the composer for a version for piano solo.
