Note 26 — Chapter IX · SONATA-FORM II.

Even in Haydn, however, the second themes remain generally rather rudimentary (see the analysis of his "Surprise Symphony," later in this chapter). In many cases his second theme is hardly more than a variant of the first; as for example in the two pianoforte sonatas in E-flat major. In the first movement of his "Paukenwirbel" Symphony, however, there is a very distinct second theme, and in many other movements the student will note a marked tendency toward definition.
