The compositions by Johann Sebastian Bach that had been printed during his lifetime were nearly exclusively instrumental works. Moreover, by the time Bach died in 1750 it was forgotten that a few of his vocal works (BWV 71, BWV 439–507...) had indeed been printed in the first half of the 18th century. In the period between the publication of "The Art of Fugue" in the early 1750s, and the publication of further works from 1900, only one group of Bach's works was published: his four-part chorales.
