Concerto-Sonata Form

T begins the same as in expo. I. The soloist enters (m. 87), starting the mod. process and lengthening the trans.
A B7 chord (m. 90) is introduced , setting up E major.
The remainder of T serves to prolong the new dominant, strengthened by an It6 chord (m. 96).
S retains the timbral contrast between phrases (pno. vs. orch.), but essentially remains the same as in expo. I.
The first 14 meas. of K (m. 115-128) are about the same.
The final cadence is extended via scalar passages in the solo voice.
