As the lower note of the R. H. chord GC (→GE1) erroneously has b. Although the very fact of making a mistake is doubtless, it is not clear whether the copyist forgot to put in a 
sign raising b to b sharp or whether he made the Terzverschreibung error. The g sharp that occurs in EE and FE is a strong argument for the latter possibility and this is how the error was corrected in GE2.
