I just updated all the scores with a footnote about the turn symbol. I am using it the way it is usually used in Irish books, to mean "play one note above and back to the printed note." Technically a mordent symbol should be used for a note above ornament, but I guess I like how the turn looks, just like the Irish! Speaking of Irish musicians, they call this ornament a cut...as if you took one note and cut it in two by adding the grace note.
Thank you to Mr. Maurer, for pointing out this issue!
