In A the 
asterisks are put either after the 3rd crotchet in the bar (or a corresponding it rest) or before, depending on the fact whether the entire bar is based on the same chord or not. In FE the differentiation was lost – all signs are put either under or slightly after the 3rd crotchet (rest), whereas the differences are not related to the notation of A (or – consequently – to the harmony). The remaining editions reproduce the version of FE more or less accurately, although in GE the signs are generally placed after the 3rd crotchet, while in EE – rather below. In our transcriptions of particular sources, we assume that the asterisks placed in an inaccurate manner – most often slightly after the 3rd crotchet – are considered by us to be compatible with the majority of such signs in a given phrase of a discussed source.
A few particular situations – bars 4, 15, 20, 22, 24, 29, 30 and 31 – are discussed separately.
