Turns comes in different shapes. I really forgot the way it is played. Is there a rule of the thumb? Busy with a piece, I see two different shapes. With the curls up and sometimes down. When does a turn start on the note below the one above the turn is notated?
In fact the whol score is just a mess. Turns all over, sometimes different in shape, sometimes replaced by common trills, sometimes by a mordent. I assume that Chopin never intended this or notated this in the original.
Any advice will be highly appreciated,
