these are very clear, graceful variations, which require an extremely nice, delicate execution; and, especially, a complete mechanical mastery of their various difficulties. Although these variations may seem to you too easy, I am governed in the selection of them by the maxim that "what one would learn to play finely must be below the mechanical powers of the pupil." The theme of the Italian song, which is the basis of these variations, is very well chosen, and you must take great pains to execute it as finely as possible, and to produce a singing effect upon the piano-forte. After the piece is thoroughly learned, you will be greatly aided in the production of this imitation of singing by the careful and correct use of the pedal which raises the dampers. The theme does not offer great mechanical difficulties; but it requires a loose, broad, full, and yet tender touch, a good portamento, and a clear and delicately shaded delivery; for you must remember that "in the performance of a simple theme the well-taught pupil may be recognized."
