"He would write out the full score from the short score with everything, even new counterpoints in ink in the final draft;...he never crossed anything out. If he made a mistake he would take out a pen-knife, carefully erase it, smooth the spot with his nail and write the note over the spot. But there were very few corrections to be done, for he rarely made a mistake. Even with transposing instruments, where it is easy to go wrong. He would write just as the likes of us write a letter."
