The class begins working on the instrumental part of the accompaniment: the pulse must be "alla breve", the trill is very short and played from the upper note (D).
This third movement is Adagio, so the tempo is calmer. In a certain passage, the notes should not be so short and the sforzato must be clearer.
The first clarinet has a role of soloist and has to stand out more in the dynamic aspect. On the contrary, the oboe and the rest of the octet must play softer, in piano, but with clearer articulation. As a conclusion, the students should play "aufspielen" (with more intention) during the whole movement.
