You have learned enough for to-day; but you may play the other variations, with the whole finale, straight through, that you may not get into the habit of stopping at the difficult passages which you have already learned.
_Fourth Lesson._ New exercises for striking stretches, and for the extension of the hand and fingers; but this must be done prudently, that the sound touch, which is always of the first importance, shall not be endangered.

Besides this, the repetition of the exercises learned in the preceding lessons; but all to be played with a certain shading and delicacy.

We will to-day begin at the beginning, with the introduction.
I will now make amends for my want of regularity, and show you that I can begin at the beginning, like other people; but all in good time.
To-day, in those portions of which you have acquired a mastery, we will give particular attention to the expression, and to the correct use of the pedal.

If what I suggest to you with regard to the shading at any place does not entirely correspond to your understanding of the piece, or to your feeling, you must at once express your difference of opinion, and ask me for the reason of my view.

You, perhaps, do not like to play this place _crescendo_, but _diminuendo_.
