In its broadest terms, sonata form can be described as the harmonic movement from tonic ( I ) to dominant ( V ) and back to tonic. This tonal map helps to organize the different themes definitive of sonata form (primary theme, transition, secondary theme, and closing). While sonata form has a definite structure, its limitations are minimal. This form satisfied the appetite for order, while allowing composers to display their creative genius. A display of this creative genius can be found in Mozart's Piano Sonata in F major, K. 332. Mozart makes use of sonata form in the first movement of this work for solo piano.
Taking a broad look at this opening movement, we see the tonal passage of tonic-dominant-tonic. The piece starts in F major, begins transitioning toward the dominant (where it arrives in m.41) and then develops (m. 94-133) back to the tonic. Taking a closer look at the composition reveals idiosyncrasies that show Mozart's skill. He begins the work in a simple fashion- a singable melody placed on top of an Alberti bass harmonic progression. The playful energy continues as Mozart mimics natural horns as they call for the hunt (m.12-14). Mozart plays with the emotions of his listeners by taking a sharp turn into a minor tonality, using dissonances and fully diminished chords. All of this in twenty two measures. A further investigation would give light to more of the genius decisions made by the composer, but it does not take a sharp eye to notice how Mozart capitalizes on the flexible structure of sonata form to demonstrate his compositional ability.
