Verbal indications

b. 1

composition: Op. 50 No. 2, Mazurka in A♭ major

..

We replace the Chopinesque abbreviation m.v., currently defunct, with the indication in full wording, i.e. mezza voce. A similar action was performed already in EE.

b. 62

composition: Op. 50 No. 2, Mazurka in A♭ major

No indication in A1 (→FEEE)

cresc. in GE

..

In the main text we include the cresc. marking, which is one of the indications specifying the performance indications introduced in [A2] or perhaps only just in the proofreading of GE1. The latter is indicated by the absence of a respective addition in b. 78, which was probably marked as repetition of b. 62 in [A2], just like in A1 (however, other explanations are also likely, e.g. an oversight of the engraver).
