..

We give the time signature marking after CLI and Ap. Although FE (→GE,EE) has , it is hard to assume that the change in time signature was done on purpose, if in FE the  marking was not used in the Etudes even once – contrary to the manuscripts – cf. Etudes in C minor, No. 4, F major, No. 8 and C minor, No. 12. The phenomenon appears also in other pieces, even in totally clear situations, e.g., in Etudes in F minor, Op. 25 No. 2, D major, Op. 25 No. 8 or F minor, Dbop. 36 No. 1.
