Soft timbre, accurate pitch, clean pronunciation, clear and smooth links, simple and full staccato are the pursuit of every player. However, in actual performance, especially in the initial learning process, there are often cases of unclear articulation, discontinuity and continuous staccato. These phenomena are directly related to non-standard holding posture, excessive finger raising and rigid finger pressing. Some players rely on their hands to "help" when they can't breathe. They press the instrument with their hands and wrap the flute head with their lips, and raise their fingers too high and press them too heavily. As a result, the finger muscles and the muscles of the lower arm and upper arm are tense. The finger is stiff and the fingers are not flexible. once they meet the fast rhythm, they can't blow the sound clearly, resulting in unclear articulation. The phenomenon of continuous discontinuity and discontinuity. The rigid arm and shoulder muscles also make the breath which should be unblocked and lowered stiff, lose the control of "lower fulcrum", and cause the tone stiffness, weakness and tightness. In addition, such posture and the weight of the instrument itself cause instability of the instrument, which affects the stability of the contact between the flute and the lips, and further forms a vicious circle of playing. To get rid of these problems, it is necessary to establish a relaxed and natural playing state. When holding a musical instrument, the shoulders must relax and droop naturally. When the muscles of the big and small arms are relaxed, the fingers will bend naturally and slightly to press keys. The left thumb is placed on the fingertip of the lower end of the overtone key on the back of the saxophone, and the tip of the thumb is slightly extended. When using the overtone key, just press the fingertip up gently. The right thumb is placed under the middle of the saxophone to support the tube. The hands are solitary when pressing the keys, and close to the sound keys, using the finger belly keys. The thumb of the left hand is the focus, the thumb of the right hand is the support point, and the other fingers are relaxed. When pushing the button, we should give full play to the role of the finger support of the musical instrument, and try to put some strength on the finger support of the musical instrument. The finger should not be too heavy when pressing the key, in order to prevent the rigidity of the finger and not too high when lifting the finger. We should give full play to the flexible role of the major joints and promote the coordinated movement of the two and three joints. only under the premise of relaxing the natural finger, can we ensure the natural fluency of the performance.
