I have this piece from Bach called "no. 35, BWV 514" and there are these ornaments that i don't understand. Like the grace note at bar 11 where there is a eight grace note and a trill notation over the note. I know that the grace note should take half of the value of the principal note, but i don't know how to play it when the grace note has a trill mark.

Then at bar 15 there is a trill but how should it be played and end on the G note without messing the trill up.

    There are plenty of recordings of this. Have you given yourself the opportunity to listen to any?

  • Mmmh, i haven't tried to listen to recordings of this piece. Maybe i can try to replicate how they play, thanks. Commented May 10, 2020 at 20:08
  • It is not always true, even in music of that period, that the grace note takes up half the note length. Commented May 11, 2020 at 15:02

J.S.Bach's own guide to ornaments, written for his son Wilhelm Friedemann, is here, and there's a transcription of it here, which is easier to read.
