One of the most important factors for the success of clarinet students is whether the technique training method of pressing the sound hole with both hands is appropriate. If the fingering posture is not correct at the beginning stage, the later development will have a negative impact, such as greatly reducing the efficiency and achievement of later learning, or even may cause occupational diseases. Therefore, every teacher should pay special attention to the training of finger position, and help students to overcome the difficulties in the early stage of learning with great patience.
