J.S. Bach - BWV 567 - Praeludium C-dur / C major *spurious* 

Deemed authentic In BWV I(1950) & II(1990) but in BWV IIa(1998) moved to Anhang(=Appendix)III, Bach falsely ascribed, p.468 JLK(Johann Ludwig Krebs), Komponist=composer. Truly atypical for Bach with melodic-harmonic construction inferior to his known works.

Sounds like a pupil or relative familiar with Bach's music wrote this

I:oo, atypical to Bach, but his pupil JL Krebs use the chord.
