The timbres played by different professional ensembles are quite different because of the differences in some of the instruments, such as the timpani (the difference between the drum head and the hammer), the difference in the structure of the German style clarinet and the French clarinet, the double bass (small bow vs. difference between bows), etc. 

These differences not only bring the differences in the timbre of the French and German style clarinet, but also the great differences in the way of pronunciation. The difference in structure between the German style clarinet and the French clarinet results in obvious differences in the timbre of the two clarinets.

Compared with French instruments, the barrel size of German style clarinet is wider and thicker. However, the mouthpiece of the German style clarinet is smaller, so the airflow is gathered through the air inlet, and then transmitted to the tube body to bring a fuller vibration, so that the sound quality of the pronunciation will be more concentrated and the sound will be stronger. In the tones of the German style clarinet, there is a distinct wooden "core" characteristic.

Through the above introduction and analysis of German style clarinet, hope it helps you.
