As professor of cello and piano, Nölck composed over three hundred works that included concertos, whims, waltzes, concertina, gavottes, minuets, mazurkas, funeral marches, and the like.
However, due to the two World Wars in Germany and political divisions of the nineteenth and twentieth centuries, only his works produced in Venezuela have been recovered.
[1] Nölck studied music at the Bernuthsche Konservatorium in Hamburg, Germany, which was founded 1 October 1873, by Julius von Bernuth [de] (1830–1903).
The conservatory was once located at 15 Wexstrasse on the ground floor and at another time, at grosse Theaterstrasse 44 in the home of the piano manufacturer, Otto Börs.
[4] Nölck married Franziska Lewis, the first girlfriend of one of his close friends and conservatory classmate, Hugo Rüter.
