1:26:22 I have to call foul on this explanation. I agree with the rule, but not the explanation...the reason he added the grace note in this case is that he wants the trill to consist of four notes, whereas NORMALLY a trill on an eighth note followed by a two-note termination written in sixteenth notes would consist of a three-note trill starting on the main note (see, for instance, the second theme of Mozart K. 533 first mvt.). How would you then explain the fact that Beethoven continues to write the grace note in the subsequent measures, when trill is not preceded by the same note?
Furthermore, with the argument proposed by Levin, how do you explain Mozart's consistent use of an upper grace note before every trill in the second movement of his early C Major Symphony (K. 128)?
Again, I agree with the rule, but not the explanation.

Where is it mentioned that a trill on an eighth note followed by a two-note termination written in sixteenth notes would consist of a three-note trill starting on the main note?

@@avivdor1454 Paul Badura-Skoda mentioned it in his book. Of course, he is not a primary source. But what I would say to that is: what's your alternative?

[@avivdor1454]

@@GSHAPIROY Thanks for providing the source. The alternative would be a "normal" trill at the time that would start from the upper note and have a termination.
My explanation for the grace note above the trill is that it's meant to emphasize and lengthen the appogiatura (the upper note) that you'd normally play very quickly on a short note. I don't have any proof of that it just makes sense to me based on the sources I'm familiar with.
