For Brahms, folk songs were sources of musical inspiration, not subjects for academic study. The songs from Books 6 and 7 of the Deutsche Volkslieder exemplify how Brahms' distinctive and expressive accompaniments brought unique qualities to these songs, how he intensified certain verses to draw out their power, or allowed the piano it's own revealing melodic phrases. In Book 7 the songs are divided between a lead singer and a chorus, adding fresh musical possibilities. In the Volkskinderlieder ('Children's Folk Songs') Brahms' economy and deftness turn lullabies into works of art.
