→Mozart's memory: rewrite per sources. Whatever really happened, regarding the "second visit", more recent sources (1995 is a while back...) agree that this part is most probably a later invention.
One may question whether, in these instances, Mozart remembered the entire keyboard part note-for-note. Given the independent testimony (above) for his ability to fill in gaps through improvisation, it would seem that Mozart could have done this as well in performing the violin sonatas.
Another instance of Mozart's powerful memory concerns his purported memorization and transcription of [[Gregorio Allegri]]'s ''[[Miserere (Allegri)|Miserere]]'' in the [[Sistine Chapel]] as a 14-year-old.<ref>Doubts have been cast as to the veracity of this story. See [[Miserere (Allegri)#History]] for further details.</ref> Here again, various factors suggest great skill on Mozart's part, but not a superhuman miracle.
