Mozart 3 2nd mvmt trills
Any opinions on the trills in Mozart 3, 2nd movement, m. 9 and m. 32? According to the notes in the Barenreiter edition, they have been traditionally performed incorrectly as whole step trills and should both be half step trills. My son's teacher likes one as a half step and the other as a whole step. I feel like I could make an argument either way based on different factors (performance practice and harmonically). Opinions or thoughts?
Hi Susan. My feeling is that the passage that starts in measure 9 is in A major, hence the G sharp, and the passage that starts in measure 32 is in D major, hence the C sharp. But I know nothing about harmony so this reply is just to draw attention to your question. Scott Cole may answer if he has time.
Just curious, what is the reasoning given by that Barenreiter editor?
In my edition, which was edited by my teacher, Rene Benedetti, the measure 9 trill is marked specifically as G sharp, and the measure 32 trill is not marked, indicating C sharp. Generally, I assume that unless the trill is marked, it should reflect the key signature, and my version adheres to that. However, as Jean stated, it would be interesting to know how the Barenreiter editor arrived at his conclusion.
Your ears should be able to inform you - especially depending on what precedes and what follows.
Scott Cole has nothing BUT time. And, as we know, opinions.
I always admire your reasoning, Scott. Thanks as well.
All it says in the Barenreiter is this, "Contrary to tradition, half-step trills are called for in the 2nd movement, mm. 9 and 32 (the unnecessary sharp in m. 33 should be interpreted as another indication of this.)" That is in the editor's notes to the edited part. There is nothing in the urtext or piano score about it.
I think that without seeing the autograph manuscript (and who knows if it still exists; I cannot find it on IMSLP and the urtext there is silent), an argument can be made for either choice in both measures. As Barenreiter acknowledges, its suggestion is contrary to tradition. However, I would say that your son can do whatever works best for him. Enjoy the wonderful piece!
Just looked at the urtext again. The trill in measure 9 appears to be where the key change occurs. You go from D major chords to A major chords at that point. With regard to measure 32, you have been in G major, and it appears that at the point of the trill, you are getting back into D. So, I would go with the sharps for the trill notes. However, I can see other possibilities people have described.
