I'm sorry. This just doesn't make good sense to me.You study the score before even hitting the first key. You know you can either play it or you can't. Don't have to be Albert Einstein to figure that out.If it is out of your reach, you lay it aside and pick up something else.I very much dislike struggling to learn things that are maddeningly out of reach -- a sinkhole for time and only dismal chances of a professional sound at the end of it.I wish you luck in taking on your "dinosaur." I suspect you will need it.Not intending to be rude--Regards--
