In this second movement of the Serenade, Professor Thunemann gives some indications about tempo, dynamics, articulation and character: the pulse must be interiorised in one beat; the dynamics are growing step by step, without abrupt changes. The fortepiano is almost a sostenuto; in the horn part, the notes must be played more articulated, more separated.
Talking about phrasing, Thunemann says that, before a new theme appears, it is recommended pausing, the idea is to emphasize the new material.
In general, the phrasing of the movement needs more direction and the students have to play with more energy.
At the end of the masterclass, Thunemann comments that the beginning of the Menuetto in the Da Capo part is played in a different way, in relation to the first time. So it is necessary to unify both of them. The character is more animato, with more energy, and as the third beat comes too late it sounds a little tired). The phrasing in the second part of the Menuetto has more direction for continuing in the following bar. Because of that, it is better if the students play it play it with more intention.
