The slurs in the L.H. appeared in the notation of the Etude together with the transition to two times bigger rhythmic values – in AT, where the part of the L.H. is written with quaver triplets, there are no slurs. However, the consistency with which Chopin wrote them throughout the entire piece may mean that their function probably exceeds the indication of a rhythmic grouping, suggesting also the legato articulation.
