In the didactic material there are also geometrical solids--pale blue in color--a sphere, a prism, a pyramid, a cone, a cylinder. The most attractive way of teaching a child to recognize these forms is for him to touch them with closed eyes and guess their names, the latter learned in a way which I will describe later. After an exercise of this kind the child when his eyes are open observes the forms with a much more lively interest. Another way of interesting him in the solid geometrical forms is to make them _move_. The sphere rolls in every direction; the cylinder rolls in one direction only; the cone rolls round itself; the prism and the pyramid, however, stand still, but the prism falls over more easily than the pyramid.
[Ill.u.s.tration: FIG. 26.--SOUND BOXES.]
Little more remains of the didactic material for the education of the senses. There is, however, a series of six cardboard cylinders, either closed entirely or with wooden covers. (Fig. 26.)
When these cases are shaken they produce sounds varying in intensity from loud to almost imperceptible sounds, according to the nature of the objects inside the cylinder.
There is a double act of these, and the exercise consists, first, in the recognition of sounds of equal intensity, arranging the cylinders in pairs. The next exercise consists in the comparison of one sound with another; that is, the child arranges the six cylinders in a series according to the loudness of sound which they produce. The exercise is a.n.a.logous to that with the color spools, which also are paired and then arranged in gradation. In this case also the child performs the exercise seated comfortably at a table. After a preliminary explanation from the teacher he repeats the exercise by himself, his eyes being blindfolded that he may better concentrate his attention.
We may conclude with a general rule for the direction of the education of the senses. The order of procedure should be:
(1) Recognition of _ident.i.ties_ (the pairing of similar objects and the insertion of solid forms into places which fit them).
(2) Recognition of _contrasts_ (the presentation of the extremes of a series of objects).
(3) Discrimination between objects very _similar_ to one another.
To concentrate the attention of the child upon the sensory stimulus which is acting upon him at a particular moment, it is well, as far as possible, to _isolate_ the sense; for instance, to obtain silence in the room for all the exercises and to blindfold the eyes for those particular exercises which do not relate to the education of the sense of sight.
The cinematograph pictures give a general idea of all the sense exercises which the children can do with the material, and any one who has been initiated into the theory on which these are based will be able gradually to recognize them as they are seen practically carried out.
It is very advisable for those who wish to guide the children in these sensory exercises to begin themselves by working with the didactic material. The experience will give them some idea of what the children must feel, of the difficulties which they must overcome, etc., and, up to a certain point, it will give them some conception of the interest which these exercises can arouse in them. Whoever makes such experiments himself will be most struck by the fact that, when blindfolded, he finds that all the sensations of touch and hearing really appear more acute and more easily recognized. On account of this alone no small interest will be aroused in the experimenter.
For the beginning of the education of the musical sense, we use in Rome a material which does not form part of the didactic apparatus as it is sold at present. It consists of a double series of bells forming an octave with tones and semitones. These metal bells, which stand upon a wooden rectangular base, are all alike in appearance, but, when struck with a little wooden hammer, give out sounds corresponding to the notes doh, re, mi, fah, soh, lah, ti, doh, doh [sharp], re [sharp], fah [sharp], soh [sharp], lah [sharp].
[Ill.u.s.tration: Musical Scale (Chromatic)]
[Ill.u.s.tration: FIG. 27.--MUSICAL BELLS.]
One series of bells is arranged in chromatic order upon a long board, upon which are painted rectangular s.p.a.ces which are black and white and of the same size as the bases which support the bells. As on a pianoforte keyboard, the white s.p.a.ces correspond to the tones, and the black to the semitones. (Fig. 27.)
At first the only bells to be arranged upon the board are those which correspond to the tones; these are set upon the white s.p.a.ces in the order of the musical notes, doh, re, mi, fah, soh, lah, ti, doh.
To perform the first exercise the child strikes with a small hammer the first note of the series already arranged (doh). Then among a second series of corresponding bells which, arranged without the semitones, are mixed together upon the table, he tries, by striking the bells one after the other, to find the sound which is the same as the first one he has struck (doh). When he has succeeded in finding the corresponding sound, he puts the bell thus chosen opposite the first one (doh) upon the board. Then he strikes the second bell, _re_, once or twice; then from among the mixed group of bells he makes experiments until he recognizes _re_, which he places opposite the second bell of the series already arranged. He continues in the same way right to the end, looking for the ident.i.ty of the sounds and performing an exercise of _pairing_ similar to that already done in the case of the sound-boxes, the colors, etc.
Later, he learns in order the sounds of the musical scale, striking in rapid succession the bells arranged in order, and also accompanying his action with his voice--doh, re, mi, fah, soh, lah, ti, doh. When he is able to recognize and _remember_ the series of sounds, the child takes the eight bells and, after mixing them up, he tries by striking them with the hammer, to find _doh_, then _re_, etc. Every time that he takes a new note, he strikes from the beginning all the bells already recognized and arranged in order--doh, _re_, doh, re, _mi_; doh, re, mi, _fah_; doh, re, mi, fah, _soh_, etc. In this way he succeeds in arranging all the bells in the order of the scale, guided only by his ear, and having succeeded, he strikes all the notes one after the other up and down the scale. This exercise fascinates children from five years old upwards.
If the objects which have been described const.i.tute the didactic material for the beginnings of a methodical education of the auditory sense, I have no desire to limit to them an educational process which is so important and already so complex in its practise, whether in the long established methods of treatment for the deaf, or in modern physiological musical education. In fact, I also use resonant metal tubes, small bars of wood which emit musical notes, and strings (little harps), upon which the children seek to recognize the tones they have already learned with the exercise of the bells. The pianoforte may also be used for the same purpose. In this way the difference in _timbre_ comes to be perceived together with the differences in tone. At the same time various exercises, already mentioned, such as the marches played on the piano for rhythmic exercises, and the simple songs sung by the children themselves, offer extensive means for the development of the musical sense.
To quicken the child"s attention in special relation to sounds there is a most important exercise which, contrary to all attempts made up to this time in the practise of education, consists not in producing but in eliminating, as far as possible, all sounds from the environment. My "lesson of silence" has been very widely applied, even in schools where the rest of my method has not found its way, for the sake of its practical effect upon the discipline of the children.
The children are taught "not to move"; to inhibit all those motor impulses which may arise from any cause whatsoever, and in order to induce in them real "immobility," it is necessary to initiate them in the _control_ of all their movements. The teacher, then, does not limit herself to saying, "Sit still," but she gives them the example herself, showing them how to sit absolutely still; that is, with feet still, body still, arms still, head still. The respiratory movements should also be performed in such a way as to produce no sound.
The children must be taught how to succeed in this exercise. The fundamental condition is that of finding a comfortable position, _i.e._, a position of equilibrium. As they are seated for this exercise, they must therefore make themselves comfortable either in their little chairs or on the ground. When immobility is obtained, the room is half-darkened, or else the children close their eyes, or cover them with their hands.
It is quite plain to see that the children take a great interest in the "Silence"; they seem to give themselves up to a kind of spell: they might be said to be wrapped in meditation. Little by little, as each child, watching himself, becomes more and more still, the silence deepens till it becomes absolute and can be felt, just as the twilight gradually deepens whilst the sun is setting.
Then it is that slight sounds, unnoticed before, are heard; the ticking of the clock, the chirp of a sparrow in the garden, the flight of a b.u.t.terfly. The world becomes full of imperceptible sounds which invade that deep silence without disturbing it, just as the stars shine out in the dark sky without banishing the darkness of the night.
It is almost the discovery of a new world where there is rest. It is, as it were, the twilight of the world of loud noises and of the uproar that oppresses the spirit. At such a time the spirit is set free and opens out like the corolla of the convolvulus.
And leaving metaphor for the reality of facts, can we not all recall feelings that have possessed us at sunset, when all the vivid impressions of the day, the brightness and clamor, are silenced? It is not that we miss the day, but that our spirit expands. It becomes more sensitive to the inner play of emotions, strong and persistent, or changeful and serene.
"It was that hour when mariners feel longing, And hearts grow tender."
(Dante, trans. Longfellow.)
The lesson of silence ends with a general calling of the children"s names. The teacher, or one of the children, takes her place behind the cla.s.s or in an adjoining room, and "calls" the motionless children, one by one, by name; the call is made in a whisper, that is, without vocal sound. This demands a close attention on the part of the child, if he is to hear his name. When his name is called he must rise and find his way to the voice which called him; his movements must be light and vigilant, and so controlled _as to make no noise_.
When the children have become acquainted with _silence_, their hearing is in a manner refined for the perception of sounds. Those sounds which are too loud become gradually displeasing to the ear of one who has known the pleasure of silence, and has discovered the world of delicate sounds. From this point the children gradually go on to perfect themselves; they walk lightly, take care not to knock against the furniture, move their chairs without noise, and place things upon the table with great care. The result of this is seen in the grace of carriage and of movement, which is especially delightful on account of the way in which it has been brought about. It is not a grace taught externally for the sake of beauty or regard for the world, but one which is born of the pleasure felt by the spirit in immobility and silence. The soul of the child wishes to free itself from the irksomeness of sounds that are too loud, from obstacles to its peace during work. These children, with the grace of pages to a n.o.ble lord, are serving their spirits.
This exercise develops very definitely the social spirit. No other lesson, no other "situation," could do the same. A profound silence can be obtained even when more than fifty children are crowded together in a small s.p.a.ce, provided that _all_ the children know how to keep still and want to do it; but one disturber is enough to take away the charm.
Here is demonstration of the cooperation of all the members of a community to achieve a common end. The children gradually show increased power of _inhibition_; many of them, rather than disturb the silence, refrain from brushing a fly off the nose, or suppress a cough or sneeze. The same exhibition of collective action is seen in the care with which the children move to avoid making a noise during their work. The lightness with which they run on tiptoe, the grace with which they shut a cupboard, or lay an object on the table, these are qualities that must be _acquired by all_, if the environment is to become tranquil and free from disturbance. One rebel is sufficient to mar this achievement; one noisy child, walking on his heels or banging the door, can disturb the peaceful atmosphere of the small community.
LANGUAGE AND KNOWLEDGE OF THE WORLD
The special importance of the sense of hearing comes from the fact that it is the sense organ connected with speech. Therefore, to train the child"s attention to follow sounds and noises which are produced in the environment, to recognize them and to discriminate between them, is to prepare his attention to follow more accurately the sounds of articulate language. The teacher must be careful to p.r.o.nounce clearly and completely the sounds of the word when she speaks to a child, even though she may be speaking in a low voice, almost as if telling him a secret. The children"s songs are also a good means for obtaining exact p.r.o.nunciation. The teacher, when she teaches them, p.r.o.nounces slowly, separating the component sounds of the word p.r.o.nounced.
But a special opportunity for training in clear and exact speech occurs when the lessons are given in the nomenclature relating to the sensory exercises. In every exercise, when the child has _recognized_ the differences between the qualities of the objects, the teacher fixes the idea of this quality with a word. Thus, when the child has many times built and rebuilt the tower of the pink cubes, at an opportune moment the teacher draws near him, and taking the two extreme cubes, the largest and the smallest, and showing them to him, says, "This is large"; "This is small." The two words only, _large_ and _small_, are p.r.o.nounced several times in succession with strong emphasis and with a very clear p.r.o.nunciation, "This is _large_, large, large"; after which there is a moment"s pause. Then the teacher, to see if the child has understood, verifies with the following tests: "Give me the large one. Give me the _small_ one." Again, "The large one." "Now the small one." "Give me the large one." Then there is another pause. Finally, the teacher, pointing to the objects in turn asks, "What is this?" The child, if he has learned, replies rightly, "Large," "Small." The teacher then urges the child to repeat the words always more clearly and as accurately as possible. "What is it?"
"Large." "What?" "Large." "Tell me nicely, what is it?" "Large."
_Large_ and _small_ objects are those which differ only in size and not in form; that is, all three dimensions change more or less proportionally. We should say that a house is "large" and a hut is "small." When two pictures represent the same objects in different dimensions one can be said to be an enlargement of the other.
When, however, only the dimensions referring to the section of the object change, while the length remains the same, the objects are respectively "thick" and "thin." We should say of two posts of equal height, but different cross-section, that one is "thick" and the other is "thin." The teacher, therefore, gives a lesson on the brown prisms similar to that with the cubes in the three "periods" which I have described:
_Period 1. Naming._ "This is thick. This is thin."
_Period 2. Recognition._ "Give me the _thick_. Give me the _thin_."
_Period 3. The p.r.o.nunciation of the Word._ "What is this?"
There is a way of helping the child to recognize differences in dimension and to place the objects in correct gradation. After the lesson which I have described, the teacher scatters the brown prisms, for instance, on a carpet, says to the child, "Give me the thickest of all," and lays the object on a table. Then, again, she invites the child to look for _the thickest_ piece among those scattered on the floor, and every time the piece chosen is laid in its order on the table next to the piece previously chosen. In this way the child accustoms himself always to look either for the _thickest_ or the _thinnest_ among the rest, and so has a guide to help him to lay the pieces in gradation.
When there is one dimension only which varies, as in the case of the rods, the objects are said to be "long" and "short," the varying dimension being length. When the varying dimension is height, the objects are said to be "tall" and "short"; when the breadth varies, they are "broad" and "narrow."
Of these three varieties we offer the child as a fundamental lesson only that in which the _length_ varies, and we teach the differences by means of the usual "three periods," and by asking him to select from the pile at one time always the "longest," at another always the "shortest."
The child in this way acquires great accuracy in the use of words. One day the teacher had ruled the blackboard with very fine lines. A child said, "What small lines!" "They are not small," corrected another; "they are _thin_."
