The Technical Demands of the Piece
"The next consideration should be the execution of the right notes. A careless prima-vista reading often leads the pupil to play notes quite different from those actually in the piece. It is astonishing how often some pupils are deceived in this matter. Until you have insured absolute accuracy in the matter of the notes you are not in condition to regard the other details. The failure to repeat an accidental chromatic alteration in the same bar, the neglect of a tie, or an enharmonic interval with a tie are all common faults which mark careless performances. After the piece has been read as a whole and you have determined upon the notes so that there is no opportunity for inaccuracy from that source you will find that the best way to proceed is to take a very small passage and study that passage first. For the inexperienced student I should suggest two measures or a phrase of similar length. Do not leave these two measures until you are convinced that you have mastered them. This will take a great amount of concentration. Many pupils fail because they underestimate the amount of concentration required. They expect results to come without effort and are invariably disappointed. After the first two measures have been mastered take the next two measures and learn these thoroughly. Then go back and learn measures two and three so that there may be no possibility of a break or interruption between them. Next proceed in the same way with the following four measures and do not stop until you have completed the piece.
This kind of study may take more time than the methods to which you have become accustomed, but it is by all means the most thorough and the most satisfactory. I found it indispensable in the preparation of pieces for public performances. It demands the closest kind of study, and this leads to artistic results and a higher perception of the musical values of the composition being studied. Take for instance the C Major Fantasie of Schumann, one of the most beautiful and yet one of the most difficult of all compositions to interpret properly. At first the whole work seems disunited, and if studied carelessly the necessary unity which should mark this work can never be secured. But, if studied with minute regard for details after the manner in which I have suggested the whole composition becomes wonderfully compact and every part is linked to the other parts so that a beautiful unity must result.
