My word! You really ARE a stickler on details! Only teasing...First, of all, there are all kinds of staccati. I think you only have one kind in mind. The touching-a-hot-iron one. If you listen carefully, the first and last examples, especially, use a non-legato touch to that upbeat. Even though there's pedal with it, you can hear that detached touch. I, personally, feel that's what Mozart intended. Forget about the 32nd note interpretation. It belittles the phrasing and importance of that two note slur.How would YOU play it?
