But it follows from this that there had to be a sweeping change in the generally accepted views of the universal applicability of the sonata forms. They were no doubt admirable as types of abstract design; they were examples of approximate perfection in musical organization; but, when the time came again after the sonata period to make music express ideas, it became evident, with the assistance of Beethoven’s insight, that special ideas required types of organization which were specially adapted to the ideas. Men humbly ventured on compositions which did not represent the august dignity of the sonata order. They tried in small ways to represent their feelings and ideas. They found the sonata forms much too big; the prescriptive rights of so aristocratic an organization entailing such a lot of formalities; and they had of sheer necessity to find some forms more apt and compact. The unique genius of Chopin led the way. Surrounded by an atmosphere of romanticism, and entirely free, as far as we can see, from the influence of the sonata spirit, his strange and subtle mind sought types of form which were quite independent of tradition. Very often the form seems to grow out of the musical ideas; at any rate it is easy to feel that form and utterance progressed simultaneously in his processes of inspiration. This attitude toward original methods of organization is perceptible in a very large range of his compositions--the ballads, the impromptus, the mazurkas, but in the finest and subtlest shape in the best of the preludes. There, indeed, can always be felt the underlying impulse to express some feeling or idea which is not purely and only musical, and also the exact aptness of the form in which it is expressed. Hardly any modern composers have excelled Chopin in this respect; it is his greatest contribution to the evolution of musical art. But even classical composers, composers essentially built up on the great traditions, tacitly admitted the gravitation of art back to its rightful position; Mendelssohn in his songs without words and symphonies, Schumann in vast numbers of movements of all calibres for pianoforte and even in movements of symphonies, such as the slow movement of the Rhenish and the whole of the D major; Brahms in his compact and well-considered piano pieces, and movements in his chamber music; and later on the host of experimentalizing composers in every branch of art, all bent on expressing something that stirs them, and all bent on finding special ways of organizing what they have to say. The most conclusive illustrations are naturally in the branch of song as cultivated by modern composers. Here the theories of the few faithful defenders of the old strongholds are obviously void; for it is impossible to imagine anyone being so preposterously idiotic as to try and write a song in sonata form. The scheme of organization must inevitably, in such a form of art, follow absolutely the meaning of the
