composition: Op. 28 No. 17, Prelude in A♭ major

As before, in the manuscripts and in GE various abbreviations of notation were often used.
In A (→FCGE) Chopin wrote down the majority of the groups of repeated quavers as dotted crotchets or minims provided with quaver tremolos. Such a notation is to be found in A (→FC) in b. 66 (L.H. only), 67-70, 72, 74 (L.H. only), 75-83 and in the L.H. only in b. 85 and 88-89. In addition, in FC there is a tremolo in b. 71. In GE all tremolos of FC were repeated except b. 88-89. Apart from tremolos, Chopin used in A (→FC) also / signs to mark b. 87 as a repetition of the previous one.
FCI used only / signs to mark repeating 3-quaver groups. It can be seen in b. 66, 74 and 89 and in the L.H. only in b. 72, 80 and 88. / signs were used to mark b. 85 and 87.
