In A, Chopin applied the same articulation markings system concerning L.H. crotchets as in b. 9 and subsequent – slurs over dots are present only in cases where there are no crotchets in the R.H. part (it was a thought-out system – in b. 99 Chopin removed the L.H. slur, which he considered superfluous due to a slur being present in the R.H.). The slurs added – most probably by Chopin – in the stage of proofreading FE (→GE,EE) prove that the composer was striving for precise and homogenised articulation markings concerning the crotchets in the accompaniment.
