Minims in GE3 (→GE4GE5)

Despite the fact that the correct text is actually undeniable, its correct notation in the sources appears only in GE3 (→GE4GE5). The notation of A is unclear in terms of division into voices (hands), which may have resulted in a rhythmic error of FE (→GE1GE2, →EE2EE3). In turn, at the time of adding minim stems in EE4, the G note was omitted.
