Could you help me find the 3 D's you're talking about? I thought you meant the last statement of the main Minuet theme, where my score also has a turn on the third D, but I went back and listened and the turns do appear in my recording. Maybe could you give either a measure number or minutes:seconds in my recording?
Heather - sorry this took so long. Yes, it's where the key changes from d minor back to D Major. You're right that you're doing an ornament; it's different from what we were taught back in the day for a turn (usually 4 notes instead of 2 or 3). I'm not a big stickler on ornaments myself - I think composers were just telling the performer to "ornament" the note (else why would they not just write out the notes themselves)? It was not worth mentioning, and I was probably just curious about differences in editions.
Also, I listen to these through speakers and not headphones, and occasionally do not hear as many notes as some listeners. But many of our downloading public also listen to the music this way, so there's value in doing so.
