The potential factor for cracking in composite wood clarinet is related to the body structure of the clarinet. The composite wood clarinet tube body is composed of a red inner wall and a black outer wall. The expansion coefficient of the composite wood clarinet tube inner wall is larger than that of the outer tube wall and the expansion rate is faster. When the inner wall expands excessively and the outer wall does not change much, the tension of the inner expansion will tear the outer wall, resulting in cracks. There are two potential factors that can induce composite wood clarinet cracking:

1. Play the clarinet when the temperature of the composite wood clarinet body is low, so that the inside of the tube body is heated rapidly, resulting in aggravation of the temperature difference between the inner and outer tube walls of the composite wood clarinet. In This case, special precautions should be taken in winter in cold regions.

2. Humidity changes will also cause the problem of expansion of the inner wall of composite wood clarinet. During the performance, the humidity in the composite wood clarinet tube increases greatly, which causes the inner wood to expand, but it causes cracks in the composite wood clarinet.

Through the above introduction and analysis of composite wood clarinet, hope it helps you.
