This change was perhaps only a part of that more general transformation of society by which the composer, who had previously been subject to the favor of princely patrons, became an independent individual, living in direct contact with the public at large. Music, thus freed and given an independent existence, became an expressive art and took deeper root in human experience. It lost, in this process, something of that calm, ethereal beauty it had possessed, but it gained greatly in expressiveness. In Beethoven's hands it became plastic; he enlarged the range of harmonic combinations far beyond that of Mozart, and created themes that were of wider application to human feeling. In illustration of this there will be found in Figure L, (a) a quotation from the slow movement of Beethoven's piano sonata, op. 2, no. 2, and in (b) a quotation from the slow movement of his sonata, op. 10, no. 3. These should be compared with the theme from Mozart's piano sonata in Figure XLI. The difference between the themes of Beethoven and that of Mozart is in their content rather than in their form.
The purpose of Mozart's theme is beauty; the purpose of Beethoven's themes is expressiveness, the conveyance of deep emotion. They are lacking in one essential quality of melodic beauty, namely, outline, or curve.[39] These two quotations are not representative of Beethoven's lyric genius, for he has left us many fine melodies, but they reveal a general tendency of his to seek in music an outlet for his deepest thoughts and feelings, and to sacrifice, if necessary, that beauty of outline that characterizes Mozart's finest tunes.
II. BEETHOVEN'S STYLE.
One peculiarity of Beethoven's music, due to his constant search after expressiveness rather than mere formal symmetry, is a unity and conciseness of style notably superior to that of Mozart. Many of his themes lack the perfect balance of phrases, in exact thesis and antithesis, found in Mozart's, their structure resulting rather from a logical development of the leading motive, which, by a favorite device of his, presses on, in constant repetition and with increasing vigor, to an emotional climax. The contrast between this method of treating a theme and the method of Mozart may be seen in Figure LI.
