In As, the accompanying voices are not written down, which we interpret as a repetition of the version of the analogous bar 17. However, it is not entirely certain whether it was a signal "as before" or just "like before". For this reason, we discuss independently the accompanying voices not specified in As, and the written out melodic voice.
