ten. next to e in A

ten. above chord in GE (→FE,EE,IE)

..

In the main text we keep the unconventional position of the ten. indication in A. Chopin most probably wanted to emphasise the need to hold, particularly, the e note, which does not stem from the GE notation at all (→FE,EE,IE).

b. 281

composition: (Op. 4), Sonata in C minor, Mvt IV

..

In A (→GEEE1,IE) the  restoring e1 is missing. Chopin's patent oversight was corrected only in FE and EE2.
