In As and AI the bass notes in bars 1-2 are written an octave higher than in the version prepared for print (in A one can see traces of corrections from c to C in bar 1). Lowering bass is one of frequently used interventions by Chopin at the time of elaborating original ideas – cf. bars 14, 32, 39 and 55, 65 and 81, as well as, e.g., the Waltz in D major, No. 1, bars 50 and 77.
