Only through the spirit of music can the architectonic of _Jean Christophe_ be understood. However plastic the elaboration of the characters, their effective force is displayed solely in so far as they are thematically interwoven into the resounding tide of life's modulations. The essential matter is always the rhythm which these characters emit, and which issues most powerfully of all from Jean Christophe, the master of music. The structure, the inner architectural conception of the work, cannot be understood by those who merely contemplate its obvious subdivision into ten volumes. This is dictated by the exigencies of book production. The essential caesuras are those between the lesser sections, each of which is written in a different key. Only a trained musician, one familiar with the great symphonies, can follow in detail the way in which the epic poem _Jean Christophe_ is constructed as a symphony, an Eroica; only a musician can realize how in this work the most comprehensive type of musical composition is transposed into the world of speech. Let the reader recall the chorale-like undertone, the booming note of the Rhine. We seem to be listening to some primal energy, to the stream of life in its roaring progress through eternity. A little melody rises above the general roar. Jean Christophe, the child, has been born out of the great music of the universe, to fuse in turn with the endless stream of sound. The first figures make a dramatic entry; the mystical chorale gradually subsides; the mortal drama of childhood begins. By degrees the stage is filled with personalities, with melodies; voices answer the lisping syllables of Jean Christophe; until, finally, the virile tones of Jean Christophe and the gentler voice of Olivier come to dominate the theme. Meanwhile, all the forms of life and music are unfolded in concords and discords. Thus we have the tragical outbreaks of a melancholy like that of Beethoven; fugues upon the themes of art; vigorous dance scenes, as in _Le buisson ardent_; odes to the infinite and songs to nature, pure like those of Schubert. Wonderful is the interconnection of the whole, and marvelous is the way in which the tide of sound ebbs once more. The dramatic tumult subsides; the last discords are resolved into the great harmony. In the final scene, the opening melody recurs, to the accompaniment of invisible choirs; the roaring river flows out into the limitless sea.
