I'm a bit confused as to how to play a particular series of grace notes in two pieces: Schubert's Moment Musicaux No. 3 and Debussy's Menuet. Here are the measures for reference:
In both examples, the first note of the grace note series is tied to its corresponding note on the principal note. In recordings of Moment Musicaux, it sounds like only the tied grace note is played. In recordings of Menuet, however, it seems like both the grace note and the principal note are played.
How are these intended to be played? Are the tied notes intended to be held as the tie would suggest or is the tie in fact a slur and the "tied" note is meant to be played as well? Or is the answer both, and the difference is the result of different styles/time periods of music?
