Rhythm

b. 92-93

composition: Op. 64 No 2, Waltz in C♯ minor

d3 repeated in As, AI & A (→FEEE)

d3 tied in GE & FED

..

Both source versions of the melody at the transition between the bars are almost certainly authentic. In the main text, we give the version with the repetition of the d3, written in the base source, A (→FEEE).

b. 155-156

composition: Op. 64 No 2, Waltz in C♯ minor

c2 repeated in A (→FEEE,GE1no2,GE1opGE2opGE3op)

c2 tied in FED & GE2no2

..

The tie of c2, written in FED probably by Chopin, may be considered an authentic variant with respect to the repeated note present in all remaining sources (except for GE2no2). Similarly in bars 157-158.
