At times, the pedalling of A is difficult to interpret here due to a dense notation and crossings-out. The 
mark can be particularly troublesome, since it encompasses two notes sometimes. In the main text we give a version that is compatible with the notation and that includes the harmonic changes. This is how it was reproduced by Fontana in FC; however, neither FE nor GE repeated that version. The notation of EE is also noteworthy: a mark at the beginning of the bar is followed by two 
marks, one in the middle and the other at the end of the bar. The above situation can be observed three times.
