New Problems at Every Step
The teacher in accepting a new pupil should realize that there at once arises new problems at every step. The pupil's hand, mind, body and soul may be in reality different from those of every other pupil the teacher has taught. The individual peculiarities of the hand should be carefully considered. If the hand has long, tapering fingers, with the fingers widely separated, it will need quite different treatment from that of the pupil with a short, compact, muscular hand. If the pupil's mind indicates mental lethargy or a lack of the proper early educational training, this must be carefully considered by the teacher.
If the pupil's body is frail and the health uncertain, surely the teacher will not think of prescribing the same work she would prescribe for a robust, energetic pupil who appears never to have had a sick day. One pupil might be able to practice comfortably for four and five hours a day, while another would find her energy and interest exhausted in two hours. In fact, I would consider the study of individuality the principal care or study of the teacher.
The individuality of different virtuoso performers is very marked. Although the virtuoso aspires to encompass all styles—that is, to be what you would call an "all-around" player—it is, nevertheless, the individuality of the player that adds the additional charm to the piano-recital. You hear a great masterpiece executed by one virtuoso, and when you hear the same composition played by another you will detect a difference, not of technical ability or of artistic comprehension, but rather of individuality. Rembrandt, Rubens and Vandyke might have all painted from the same model, but the finished portrait would have been different, and that difference would have been a reflection of the individuality of the artist.
