Example 17.14: whereas the development section in a
fast-movement sonata form by Haydn tends to be roughly the same
length as the surrounding exposition and recapitulation, the
development from this slow-movement sonata is less than one-third
as long as the exposition.
In these eight measures, Haydn briefl y touches on three tonal
regions ( LK , KL , and KK ) by means of a descending-third
sequential pattern. Th e fi nal dominant in m. 34 is so weakly
articulated that it is unlikely even to be perceived as an end-ing
harmony.
