Yes I think it is a good idea, just to talk about few things, not to mix all together.
This K.44 is related to Antiphon K.86 that's because this K.44 was used to prove Mozart that Martini was his teacher.
I suppose K.44 is piece well written, but I see that it is not by Mozart. It is a piece of later Renaissance, not a 1770 composition as it is written in my CD
.
But I also see that, according to the examples given in pdf, there are also mistakes in the Antiphon K.86, the one written by Mozart. That's the reason Martini wrote another version of this Antiphon. So I wonder why Mozart cannot control voices inside a vocal piece? That's strange. I see there are also errors, braking the rules of Philarmonic Academy, in the parts. I see Mozart cannot write simple imitations in K.86, he cannot control parts that produce parallel octaves, and parallelism in conducting parts, is a way to show that the composer actually wrote voices that are not indipendent. Mozart I see cannot prepare and resolve dissonancies. He used an instrumental language, but he was requested to write a vocal piece in ancient style. At least I see so in the example provided in .pdf. I see the piece also in Mozart Critical Edition. It is so, no doubts. That's very strange.
