Thank you for the update! I'm playing it right now! But there is something that has been in my mind. This is the 18th Century, isn't it? So it must be in the 1700s, but I read Rachmaninoff's piano arrangement of Liebesleid Catherine played was published in the 1900s. If it's the 1700s, then Catherine should have played something in the Classical era like Mozart's, or if you want the previous era of Baroque then Bach's.
