It is probably an exaggeration to say that this has been the hardest song thusfar, but I think it just might be accurate. According to her teacher the double stops part in this book four song is a book 8 level. I believe it. We have worked for months on this song. She had to be able to play most of the difficult parts before she could start the Vivaldi song that she has been DYING to play. So here is her today playing the 3rd Seitz Concerto. It is far from perfected and is actually missing some sections. I decided not to tell her because all the other days we tried to record it for Mom she ended up stomping off crying cause she forgot something. Maybe she'll have to record it again when it is polished.
