I love music dearly and my teacher is always satisfied with my lessons, but when I play for my friends I never make a success. They compliment me, but I feel that they do not care for my playing; even my mother says that my playing is "mechanical." How can I change it?
It is just possible that your friends and your mother may not be amenable to the high class of music which you play, but if this is not the case your affliction cannot be cured offhand. If the lack of expression in your playing should emanate from a lack of feeling in yourself, then your case would be incurable. If, however, you play "mechanically" because you do not know how to express your emotions in your playing—and I suspect it to be so—then you are curable, although there are no remedies that would act directly. I suggest that you form close associations with good musicians and with lovers of good music. By looking well and listening you can learn their modes of expression and employ them first by imitation until the habit of "saying something" when you play has grown upon you. I think, though, that you need an inward change before there can be any outward change.
The Art of Playing With Feeling
In the musical manifestations of feeling how does the artist chiefly differ from the amateur?
The artist expresses his feelings with due deference to the canons of art. Above all, he plays correctly without allowing this ever-present correctness to make his playing seem lacking in feeling. Without unduly repressing or suppressing his individuality he respects the composer's intentions by punctiliously obeying every hint or suggestion he finds in the annotations, concerning speed, force, touch, changes, contrasts, etc. He delivers the composer's message truthfully. His personality or individuality reveals itself solely in the way he understands the composition and in the manner in which he executes the composer's prescriptions.
Not so the amateur. Long before he is able to play the piece correctly he begins to twist and turn things in it to suit himself, under the belief, I suppose, that he is endowed with an "individuality" so strong as to justify an indulgence in all manner of "liberties," that is, licence. Feeling is a great thing; so is the will to express it; but both are worthless without ability. Hence, before playing with feeling, it were well to make sure that everything in the piece is in the right place, in the right time, strength, touch, and so forth. Correct reading—and not only of the notes per se—is a matter that every good teacher insists upon with his pupils, even in the earliest grades of advancement. The amateur should make sure of that before he allows his "feelings" to run riot. But he very seldom does.
Affected Movements at the Piano
Is there any justification for the swaying of the body, the nodding of the head, the exaggerated motion of the arms, and all grotesque actions in general while playing the piano, so frequently exhibited not only by amateurs but by concert players, too?
All such actions as you describe reveal a lack of the player's proper self-control when they are unconsciously indulged in. When they are consciously committed, which is not infrequently the case, they betray the pianist's effort to deflect the auditors' attention from the composition to himself, feeling probably unable to satisfy his auditors with the result of his playing and, therefore, resorting to illustration by more or less exaggerated gesture. General well-manneredness, or its absence, has a good deal to do with the matter.
