 Sometimes, the third movement of such works is the recapitulation of the first movement (one example being Franz Strauss' Horn Concerto in C Minor), making the entire work effectively a single-movement sonata.Some Classical slow movements involve a different sort of truncation, in which the development section is replaced altogether by a short retransition.This occurs in the slow movements of Mozart's quartets KV 387, KV 458, KV 465, KV 575, and KV 589.
