This sonata was composed around 1802, a point at which Beethoven experienced the crisis of encroaching deafness. From then on, the composer started to introduce innovative and bold ideas within classical framework in his musical composition to expand the expressiveness of his music. His novel approach was evident in his formal and harmonic arrangement in the first movement of Sonata Op.31 No.1. Distinctive harmonic departure from the classical sonata form convention fills the movement with drama. In classical sonata form convention, tonality is to be established in the first theme with no ambiguity so as to make contrast with the second theme, which is normally set in the dominant.

The coda (mm.295-324) consists only simple harmonies (Fig. I) of the tonic and dominant seventh, reassuring the listeners the sense of finally returning home.
Fig .H Fig .I Employing remote keys and tonicisation seem not sufficient for the composer to display his ability to expand the expressiveness of his music. Thus, Beethoven employed the technique modal mixture through out the second theme in both exposition and recapitulation. For instance, the second theme in the exposition starts with B major harmony (mm.65-69) (Fig. C). With a descending scale, the second theme swiftly changes to b minor (mm.72-79) (Fig. J). It creates abrupt change in the mood from a sweet dance-like major passage to a stormy minor one. From measure 72, b minor persists throughout the second theme except
