Good Man: Gregor Piatigorsky!

Gregor Piatigorsky (1903-1976), the celebrated Russian cellist, was also an outstanding teacher.

However, he had difficulties with a young cellist who somehow could not progress. Despite the efforts of his teacher, to show him how to play, he was constantly making mistakes.  Instead of progressing, the student played even worse.

Thinking that maybe his perfect playing is discouraging his student, Piatigorsky himself started making mistakes while playing in front of him.

- You see, it can happen to anyone - he said to his student while playing the wrong notes.

This attempt proved to be effective, and the student eventually graduated. After graduation exam, congratulations went to both of them.  

- There is no need to congratulate to Professor - disdainfully said the young cellist. - He is really a nice man, but as far as playing, the poor guy has no idea – he is constantly mistaking!
