K. 63 2/4 CAPRICCIO Allegro G-dur 2:10

Because the preceding and succeeding sections overlap, the formal transitions are extremely smooth, and musical ideas are spun out fluidly. However, the element most fitting the term "capriccio" is perhaps the key plan. In the first half, the key modulates from the tonic to the dominant, and after the repeat sign, from the dominant through a related key back to the tonic, making the key plan appear conventional at first glance. However, each half-section modulates to the parallel minor via a chromatic alteration in the upper voice just before its conclusion. Furthermore, unlike the first half, which ultimately concludes with a perfect cadence in the conventional D major, the cadence that closes the work ends in the parallel minor, G minor. This ending, which deliberately deviates from the tonic, can truly be called "capricious".
