It is now possible to add the epithet “previously” to the formulation of these sonatas as “attributed to Bach” in the title of our Urtext edition; today it is assumed that none of the three sonatas was written by “Father” Bach, but rather by his son Carl Philipp Emanuel. Yet this, too, cannot be completely and unambiguously authenticated; doubts linger. In any case, the issue does not detract from the extraordinary popularity of, for example, the Sonatas in Eb major and G minor, which have stunningly beautiful slow movements. The sonatas are part of the flautist's daily bread.
