String Quartet No.18 Kv.464 mov.4 Allegro --- Sonata form
Although this movement is in sonata form, there seems to be no second theme, and the whole movement seems to be composed of two motives included in the first theme at the beginning of the movement.
Furthermore, the second motive is derived from a motive that appears in the middle of the third movement. I don't pay much attention to the relationship of motives and themes between movements, but in this case it is so obvious that I have to point it out.
