Bach(?) is the name of the composer on the cover of the Sonata in G minor for flute (violin) and harpsichord, which has two opus numbers: BWV 1020 and H. 542.5. The two numbers refer to Johann Sebastian and Carl Philipp Emanuel, father and son, but even the family connection must be questioned. This, at least, is what editor Barthold Kuijken believes, which also explains the big question mark. According to Kuijken, the work is"much too thin for the father, untypical of Carl Philipp Emanuel, too g ood for Quantz Œ_ and no other composers suggest themselves." In additionto the question of authorship, Kuijken knowledgeably takes on all the o ther problems raised by the sources, and provides expert comments on stylistic matters. The sonata had not been available from Breitkopf until now; this new edition systematically continues KuijkenŒÍs project of revising the Bach flute sonatas.
