However, I'm not sure how I should notate it. I was trying some different things on MuseScore, and I found that the following (in the automatic playback) sounds perfect: . However, after doing some research on mordents and ornament types, this doesn't seem right, and that particular symbol looks like it should be a trill (with upper prefix), not 'mordent with upper prefix' as MuseScore calls it. EDIT: After further listening, it is just discernible that it is a full trill (with 4 notes) rather than just a mordent. At the speed of the playback I was using it was almost indiscernible.
Could anyone help me with which ornament type I should use in this case?
