[T]he firmness of structure inherent in the canonic form is perfectly compatible with genuine freedom and poetry of inspiration. - Walter Raymond Spalding

The Development, beginning in measure 132, is a striking example of how difficult it was—even for an exponent of freedom in musical expression like Schumann—to break loose from the shackles of arbitrary form.

Next to rhythm, modulation is the most stimulating and enchanting element in music. No composition of any scope can be considered truly great unlesss it abounds in beautiful modulations. Certain composers, to be sure, have in this respect more genius than others—notably Schubert, Chopin, Wagner and Franck whose music seems to waft us along on a magic carpet of delight. But just as Unity depends upon a definite basic tonality, so Variety is gained by this very freedom of modulation. … By the perfect balance in his works of these two related elements a genius may be definitely recognized.

In Schubert we do not look for the development of a complicated plot but give ourselves up unreservedly to the enjoyment of pure melodic line, couched in terms of sensuously delightful tone-color. The transitional passage of the Recapitulation (measures 231–253) illustrates Schubert's fondness for modulation just for its own sake; we care not what the objective point of the music may be—enthralled, as we are, by the magical shifts of scene.
