Thank you, that is very helpful. Do you know where I could find a list or something of all of the ratings for RCM?
It seems like a nearly impossible task to rank different pieces in difficulty anyways. Isn't it pretty subjective?
It's quite confusing this level rating. It's not logical the same piece rated 6 up to 9. Henle for me it's the least realistic of all.The numbers refer to years of study?
