I was researching and looking for the history behind a piece I am working on when I noticed something strange. On another forum much like this one they were using some kind of rating system to rate the pieces difficulty. They said it was a grade 8 and somewhere else it was called a D5. Now I am familiar with some organizations that for their own purposes rate music and usually have long lists explaining what is what but these people were not speaking in relation to an organization as far as I could tell. So is there some sort of universal system out there for rating difficulty that I have never known about? I would appreciate some input. 8| :erm:
