At the beginning of the masterclass, Professor Thunemann says that the student's sound vibrates too much, so the emission has to be more solid. Regarding the indications on the score, the student has to pay attention to the value of the notes, rhythms, and tempo - not rushing, and leave more space between every note in the staccato.
The professor also corrects the tuning in several notes and comments that it is necessary to change the reed for the high F.
The staccato is with more tongue, shorter and with more character. Regarding the dynamics, the crescendo is not so subito. Thunemann insists on not rushing the tempo and taking time in several moments, without rallentando in the final part.
When we have two similar rhythmical structures, the performance of the first structure must be slower than the performance of the second one.
