I've recently got this sheet music from my teacher and there was no explanation on how to play this. I can't seem to find anyone talking about it so I've asked here. If you got some idea, thanks.
Edit: The part I am confused with is the little symbol that goes on top of the note and why it is there, what does it change with how I play the piece. Do I need to play it any different than without it? If it helps, the piece I'm playing is Polonaise in A Minor by M.Ogiński.
