b. 1-10
We reproduce the dotted rhythms against the triplets in the R.H. in accordance with the notation of A (→FC), in which the semiquavers fall exactly over the 3rd quaver of the accompanying triplets. In FE (→EE) and GE the semiquavers were arbitrarily moved beyond the 3rd note of the triplets, contrary to the convention Chopin would use all his life. See the Nocturne in C Minor, Op. 27 No. 1, b. 5-13.
The issue of separating the top voice is related to the above problem. We adopt a notation (used in A undoubtedly on purpose, yet inconsistently) in which the top note of the chord is combined with the bottom ones with a stem. FC (→GE) and FE (→EE) considered it a superfluous complication and separated the voices. Such a notation is also to be found in CGS.
