The third movement, a scherzo, with alternating sections in 2/4 and 6/8 metre, quotes extensively from Mahler’s early song “Ablösung im Sommer” (Relief in Summer). In the trio section, a complete mood changes from playful to contemplative occurs with an offstage posthorn Bb (or flugelhorn Bb) solo. The reprise of the scherzo music is unusual, as it is interrupted several times by the posthorn melody. See The Post restaurant.---A listening guide of Symphony No. 3 - 3rd Movement with Lew Smoley.
